76. 76 4.2 College Enrollment Trends of Engineering Students 1950s-1960s: 60,000-80,000 engineering students 1970s marked the lowest number of students, at 43,000 Engineering peaked in 1980s, with around 118,000 students

77. 77 4.3 College Majors of Recent Engineering Students Of approximately 350,000 full-time undergrad engineering students, just less than 1/3 (124,000) were majoring in computer and electrical engineering Just over 32,000 were “undecided”

78. 78 4.4 Degrees in Engineering Steady decline in Engineering degrees awarded between 1986 and 1995. Since then, there have been many fluctuations, but as of data of 2000, there were 63,300 engineering degrees awarded For a long time, electrical awarded the highest number of degrees, but that was eventually replaced by mechanical engineering

79. 79 4.5 Job Placement Trends 1999-2000 was the hottest year for engineering majors to find jobs As the number of engineering students declines, employers must “fight” harder to get whatever students they can get their hands on to fill vacant positions. This has led to a very promising job placement ratio

80. 80 4.6 Salaries of Engineers On the whole, engineers make more money than any other graduate with another degree Electrical, computer, and computer science recently have led the way, with average salaries from a Bachelor degree starting at around $52,000 A Ph.D. in computer science will earn a starting average of around $84,000

81. 81 4.7 Diversity in the Profession For a long time, white males dominated engineering Recently, women, foreign nationals, and various minority students have entered colleges and universities with an engineering diploma in mind

82. 82 4.8 Distribution of Engineers by Field of Study Electrical engineering employs the highest number of engineers, nearly 25%, numbering close to 375,000 Mechanical employs almost 250,000 Civil is the next highest “populated”, with 200,000 workers

83. 83 4.11 Words of Advice from Employers Looking for graduates who possess: Excellent communication skills Teamwork Leadership Computer/Technical proficiency Hard working attitude

84. 84 Chapter 5 Global and International Engineering

90. 90 Chapter 6 Future Challenges

91. 91 6.1 Expanding World Population 1900-2000, world population climbs from 1.6 billion to 6 billion people Places new stress on conservation of resources, and gives engineers new challenges to compensate for high population

92. 92 6.2 Pollution Engineers concerned with management and the control of pollution, especially: Air pollution Water pollution and the depletion of freshwater resources Management of solid waste

93. 93 6.3 Energy It is predicted that energy usage in the Developing Countries will more than double in the next 30 years Engineers must find new ways to generate power in an effort to conserve natural resources (fossil fuels)

94. 94 6.5 Infrastructure With mass transportation an ever- present problem, engineers will be responsible in the future for designing and maintaining a system by which the transportation of raw materials, as well as the human capital that process them, can easily and efficiently move from place to place

95. 95 CHAPTER 7 Succeeding in the Classroom

96. 96 7.2 Attitude Success in an engineering curriculum depends largely on a student’s attitude and work ethic If the student’s attitude is one of failure, the student will most likely fail Keep an open mind, and be willing to “work” with the professor in order to best understand the material

97. 97 7.3 Goals Set goals that will be difficult to attain, but not impossible This will motivate the student to work hard, not just hard enough to do the minimum, but to reach their higher standard/goal Set short, intermediate, and long term goals GPA for a semester, grade on an upcoming exam, GPA for a year/college career

98. 98 7.4 Keys to effectiveness GO TO CLASS Allow 2 hrs. of study time outside of class for every hour in class Re-read sections of book covered in class Keep up with class and reading Take good notes Work lots of problems, not just the minimum amount for homework Study in groups

99. 99 7.5 Test Taking Obtain past exams Ask professor for practice exams Work problems in book Start with problems you know how to do, then work on the harder problems Skim test first, to see what will basically be covered

100. 100 7.6 Making the Most of Your Professor Don’t wait until the end of the semester to go for help If you make yourself visible in class and during office hours, the professor may remember you while grading Teaching is not professors only responsibility, often the are researchers and advisors as well, so give them the benefit of the doubt

101. 101 7.7 Learning Styles Each person’s brain is unique to him or her Proper nutrition, stress, drugs and alcohol are some of the factors that can affect a developing brain Each person is born with all the brain cells, or neurons, they will ever have (estimated at 180 billion neurons)

102. 102 7.7 Learning Styles None of us is ever too old or too dumb to learn something new! People think and memorize in several different ways

103. 103 7.7 Learning Styles Memorizing: Refers to how people assimilate new material to existing knowledge and experience How we accommodate, or change our previous way of organizing material

104. 104 7.7 Learning Styles Thinking: Refers to how we see the world, approach problems and use the different parts of our brain.

105. 105 7.7 Learning Styles We all have different learning styles Memory Languages: Auditory Visual Kinesthetic

106. 106 7.7 Learning Styles Auditory Learner: Buy a small tape recorder and record lectures Sit where you can hear the professor well Focus on what is said in class, take notes from the tape recorder later Ask the professor questions Read out loud to yourself Keep visual distractions to a minimum

107. 107 7.7 Learning Styles Visual Learner: Sit where you can see the professor and board or screen clearly Write notes during lecture with lots of pictures and meaningful doodles Rewrite notes later in a more organized fashion and highlight main ideas Write out questions to ask the professor Highlight and take notes in your book

108. 108 7.7 Learning Styles Kinesthetic Learners: TAKE Labs! Make connections between what is being said and what you’ve done in the past Talk to professor about ways to gain more hands-on experience, such as volunteering in his/her lab Use models or experiments at home

109. 109 7.7 Learning Styles Thinking Skills: Refers to how we see the world, approach problems and use the different parts of our brain Different people think differently Two hemispheres in our brain, and four quadrants generally categorize how we think

110. 110 7.7 Learning Styles

111. 111 7.8 Well Rounded Equals Effective Make sure to balance social, intellectual, and physical activities in your schedule Well rounded students are generally more effective than students with a “one-track” mind

112. 112 7.9 Your Effective Use of Time Decide in advance what to study and when Make schedules Use calendars effectively Organize tasks by priority level Stay focused on task **Remember, everyone will “fail” at some point, it’s how you respond to a failure that determines your future success or failure

113. 113 Chapter 8 Problem Solving

114. 114 8.1 Introduction Problem solving requires many “tools” and skills. Make sure that you have them, or at least know where to find them and how to use them

115. 115 8.2 Analytic and Creative Problem Solving Two basic types of problem solving involved in design process: creative and analytic More students familiar with analytic, where there is one right answer Creative problem solving has no right answers

116. 116 8.2 Analytic and Creative Problem Solving Steps that typically help w/ problem solving Make a model/figure Identify necessary, desired and given info Work backwards from answers Restate problem in one’s own words Check the solution and validate it

117. 117 8.3 Analytic Problem Solving Six steps to analytic problem solving: Define the problem and create a problem statement Diagram and describe the problem Apply theory and any known equations Simplify assumptions Solve necessary problems Verify accuracy of answer to desired level

118. 118 8.4 Creative Problem Solving Use divergence and convergence to gather and analyze ideas. Divergence is brainstorming. Convergence is analyzing and evaluating the ideas, seeking out the best possible solutions What is wrong? What do we know? What is the real problem? What is the best solution? How do we implement the solution?

119. 119 Chapter 9 Visualization and Graphics

120. 120 9.1-9.2 Visualization Visualization is often used as a mode of communication between engineers Sketches, tables, graphs, computer generated drawings, blueprints are various ways in which engineers communicate via visual mediums

121. 121 9.3 Sketching Although most final drawings are computer generated, initial and freehand sketches are vital to the design process Freehand does not mean messy. Sketches should display an adequate amount of detail, and any pertinent notes/comments pertaining to the drawing For instance, if a line is supposed to be straight, make it as straight as possible. A square will not pass for a circle.

122. 122 9.7 Graphical Communication Oblique and isometric drawings are 3D and general Orthographic drawings are 2D, more detailed, and often have dimensions for the part Object, Hidden, Centerline, and Construction are 4 common types of lines used in engineering graphics

123. 123 Chapter 10 Computer Tools

124. 124 10.1-10.6 Computer Tools for Engineers There are many aspects to the design process of a product Engineers must be competent in basic computer tools such as the internet, word processing, and basic spreadsheets Engineers will most likely be required to have some knowledge of mathematical software, such as MatLab Engineers also make computer presentations using most commonly, Microsoft PowerPoint

125. 125 10.7-10.8 Operating Systems and Programming Language Engineers may be required to have experience or be expected to be able to work in UNIX, MS-DOS, or a Microsoft Windows System Computers work on series of 1’s and 0’s, called binary code FORTRAN, BASIC, C, and C++ are all programming languages used by engineers to communicate with the computer

126. 126 Chapter 11 Teamwork Skills

127. 127 11.1 Teamwork Corporations develop teams for many reasons Projects are becoming increasingly complex Projects often span international borders, and require workers all over Projects are requiring more speed, which require more workers

128. 128 11.2 What Makes a Successful Team? A common goal Leadership Each member makes unique contributions Effective communication Creativity Good planning and use of resources

129. 129 11.4 Team Leadership Structures Traditional: One leader, who directs subordinates. Leader typically is the only one who “speaks”. Participative: Leader is closer to individual workers. Flat: There is no “leader”. All members are equal. The leadership “moves” with the situation to the worker with the most expertise in a given subject

130. 130 11.5 Decisions within a Team Consensus: All team members agree on a decision Majority Rule Minority/Committee decision Expert input

131. 131 11.7 Grading a Team Effort Did the team accomplish its goal? Were results of a high quality? If not, why? Did the team grow throughout the process? Evaluate the team leader Evaluate the other members of the team Evaluate your own contribution to the project

132. 132 Chapter 12 Project Management

133. 133 12.1 Introduction “Failure to plan is planning to fail.” A good plan is one of the most important attributes of successful teams and projects. Projects should be organized systematically.

134. 134 12.1 Eight Questions that can be Addressed with a Plan What to do first? Next? How many people? What resources? How long? Time table? Deadlines? Objectives?

135. 135 12.2 Creating a Project Charter A project summary Defining what your project is and when you will know when it is done Elements include Deliverables Duration Stakeholders Team members

136. 136 12.3 Task Definitions Identify the completion tasks to achieve the objectives and outcomes Plan Design Build Deliver

137. 137 12.3 Plans Plans should include: Who to hold accountable for progress Needed materials, resources, etc. How to determine if the project is on schedule Manage people and resources Determine the end!

138. 138 12.4 Milestones Monitoring of your plans progress Deadlines for deliverables Completion of subcomponents

139. 139 12.5 Defining Times Include the full time needed for tasks As a student, you don’t have a full eight-hour work day every day Break tasks into week segments Weekday and/or weekend Class periods Break tasks into short time periods No more than a week or two

140. 140 12.6 Organizing the Tasks Determine task relationships and sequencing Relate the task groups from your outline

141. 141 12.7 PERT Charts

142. 142 12.7 PERT Charts Each task is represented by a box containing a brief description of and duration for the task The boxes can be laid out just as the project plan is laid out Useful as a “what if” tool during planning stages

143. 143 12.8 Critical Paths The longest string of dependant project tasks Ex. – prerequisites such as the math curriculum for engineering Some tasks can be accelerated by using more people, others cannot Ex. – nine people cannot have the same baby in one month

144. 144 12.9 Gantt Charts Popular project management charting method Horizontal bar chart Tasks vs. dates

145. 145 12.9 Gantt Charts

146. 146 12.10 Details, Details Remember Murphy’s Law - “Anything that can go wrong, will.” Leave time to fix debug or fix errors

147. 147 12.10 Details, Details Don’t assume things will fit together the first time Order parts well in advance to leave time for shipping, errors, or backorders Leave time for parts malfunction Push delivery times back to a week before they’re actually due – this will help to avoid panic if things go badly

148. 148 12.11 Personnel Distribution Get the right people on the right tasks Assign people after developing a draft of the plan Balance the work between everyone Weekly updates – does everyone understand what they’re doing and is everyone still on task?

149. 149 12.12 Money and Resources Develop a budget Estimate with high, middle, and lower quality products – offer a range of solutions Extra costs Shipping Travel Extra parts such as nails, screws, resistors Material costs and labor Have someone be responsible for managing the budgets and financial aspects

150. 150 12.13 Document As You Go Document milestones as they occur Leave time at the end for reviewing, not writing

151. 151 12.14 Team Roles Roles Project Leader or Monitor Procurement Financial Officer Liaison Project Management Software

152. 152 12.14 – Project Leader or Monitor Designate a leader, or rotate leaders Monitor and track progress of milestones Maintains timelines Increases likelihood of meeting goals

153. 153 12.14 – Procurement Learns purchasing system Tracks team orders

154. 154 12.14 – Financial Officer Manages teams expenses Creates original budget Makes identifying budgetary problems easier

155. 155 12.14 – Liaison Responsible for keeping everyone informed about the progress of the plan and any changes This includes outside customers, management, professors, etc.

156. 156 Chapter 13 Engineering Design

157. 157 13.1 Engineering Design Engineering design is the process of devising a system, component, or process to meet desired needs. It is a decision making process in which the basic sciences and mathematics and engineering sciences are applied to convert resources optimally to meet a stated objective. Among the fundamental elements of the design process are the establishment of objectives and criteria, synthesis, analysis, construction, and testing….

168. 168 Chapter 16 Units

169. 169 16.1 History of Units A common denomination of units is essential for the development of trade and economics around the world National Bureau of Standards, established by Congress, adopted the English system of measurement (12 inches, etc) Majority of nations in the world today operate on the metric system because of its simplicity (multiples of 10)

170. 170 16.1 History of Units - SI Units Le Systeme International d’Unites, French for the International System of Units Improvements in the definitions of the base units continue to be made by the General Conference of Weights and Measures as science dictates

171. 171 16.2 The SI System of Units Modernized metric system adopted by the General Conference, a multi- national organization which includes the United States Built on a foundation of seven base units, plus two supplementary ones All other SI units are derived from these nine units

172. 172 16.2 The SI System of Units Multiples and sub-multiples are expressed using a decimal system Generally, the first letter of a symbol is capitalized if the name of the symbol is derived from a person’s name, otherwise it is lowercase

173. 173 16.2 The SI System of Units Base Units in the SI system Meter = m Kilogram = kg Seconds = s Ampere = A Kelvin = K Mole = mol Candela = cd

174. 174 16.3 Derived Units Expressed algebraically in terms of base and supplementary units Several derived units have been given special names and symbols, such as the newton (N).

196. 196 Chapter 18 Engineering Fundamentals

197. 197 18.1 Statics Concerned with equilibrium of bodies subjected to force systems The two entities that are of the most interest in statics are forces and moments.

198. 198 18.1 Statics Force: The manifestation of the action of one body upon another. Arise from the direct action of two bodies in contact with one another, or from the “action at a distance” of one body upon another. Represented by vectors

199. 199 18.1 Statics Moment: Can be thought of as a tendency to rotate the body upon which it acts about a certain axis. Equilibrium: The system of forces acting on a body is one whose resultant is absolutely zero

200. 200 18.1 Statics Free Body Diagrams (FBD): Neat sketch of the body showing all forces and moments acting on the body, together with all important linear and angular dimensions.

201. 201 18.2 Dynamics Separated into two sections: Kinematics Study of motion without reference to the forces causing the motion Kinetics Relates the forces on bodies to their resulting motions

202. 202 18.2 Dynamics Newton’s laws of motion: 1 st Law – The Law of Inertia 2 nd Law – F=ma 3 rd Law – F ab =-F ba Law of Gravitation

203. 203 18.3 Thermodynamics Involves the storage, transformation and transfer of energy. Stored as internal energy, kinetic energy, and potential energy Transformed between these various forms Transferred as work or heat transfer

204. 204 18.3 Thermodynamics There are many definitions, laws, and other terms that are useful to know when studying thermodynamics.

205. 205 18.3 Thermodynamics A few useful definitions: System A fixed quantity of matter Control Volume (open system) A volume into which and/or from which a substance flows Universe A system and its surrounding

235. 235 20.4 Scholarships Educational funds that do not need to be repaid Public, private, or university sources Local high school, professional groups, corporations, service organizations, government, college, etc. It is your responsibility to seek out private scholarships/grants

236. 236 20.5 Loans May be secured from lending institutions and state and federal loan programs Students who apply for financial aid will be notified of their eligibility for both student and parent federal loans Loans can be obtained from parents or relative who feel that you should repay the money that is required to put you through school

237. 237 20.6 Work-Study “Earning money the old-fashioned way” On- or off-campus employment during school Summer jobs Internships Co-ops Requires careful management of time

238. 238 20.6 Work-Study Work-Study: Employment subsidized by the federal or state government Will be listed on your financial aid award letter is you are eligible “Just Plain Work” Volunteering Full Semester Off-Campus Employment

239. 239 20.6 Work-Study Cooperative Education Academic program in which college students are employed in positions directly related to their major field of study Alternating, Parallel, and Back-to-back semesters

240. 240 20.7 Scams to Beware Do your own homework to avoid scholarship service rip-offs Check with the Federal Trade Commission (FTC) http://www.ftc.gov/bcp/menu-jobs.htm

241. 241 20.8 The Road Ahead Awaits Examine the many different sources available to you for obtaining the funds needed for your college expenses How much do you actually need? Correct forms and deadlines

242. 242 Chapter 21 Engineering Work Experience

243. 243 21.1 A Job and Experience “How do you get experience without a job, and how do you get a job without experience?” Graduate schools and employers look for experiences outside the classroom Incorporating career experience is a worthwhile consideration May extend college to 6 years Many Economic shifts have happened in a college students lifetime 1980-1983: Major Recession 1983-1986: Revival of U.S. Economy 1988-1994: Restructuring of Corporate America 1994-2001: Vigorous Rebound of Economy 2001-2003: Recession 2004- : Signs of improvement in the labor market for engineers

244. 244 21.1 A Job and Experience In good and bad times employers look for Engineers with job-related experience Engineers require less training Faster results Many different Experiences are available

245. 245 21.2 Summer Jobs Even jobs such as baby-sitting and mowing lawns is a place to start All jobs help develop basic employable skills Provide stepping stone to better, more career related jobs Skills include teamwork, communication, and problem solving Help you discover what working environments you like

246. 246 21.3 Volunteer Especially useful to freshmen and sophomores to gain experience Generally volunteer positions are with non-profit organizations Not a paid experience Useful in developing skills Able to experiment with different career related fields

247. 247 21.4 Supervised Independent Study Designed for the advanced undergraduate Preparatory for grad school or a career in Research Some are paid and others award credit Provides a unique experience Challenging in many different areas To learn more Talk to professors that share similar interests

248. 248 21.5 Internships Paid or unpaid experience for a set period of time Usually during the summer No obligations for future employment Sometimes they support other engineers Other times they are given individual projects No official evaluation or credit given Short term projects Obtain a description of these projects prior to employment to assure it is of interest Great for students with time, curriculum, and location constraints

249. 249 21.6 Co-operative Education Cooperative Education is often the preferred form of experimental Learning Co-ops are considered to be academic and are administered by the college Assignments are directly related to field of study Detailed job descriptions are used to create the best possible matches School and work are closely integrated Alternating terms of school with work at the same company Projects become more extensive throughout the experience Term in school followed by a term at work followed by a term at school and so on

250. 250 21.6 Co-operative Education Parallel co-ops is an alternative Students are partially enrolled in classes and spend 20 to 25 hours at work Difficulties arise in allowing ample time for both areas Sometimes a longer alternating approach is used Students work two consecutive semesters then attend class for a semester or two Allows for longer projects Some schools use all three methods Co-ops are rarely summer only Break between work assignments is too long Requires a three or four semester commitment

251. 251 21.6 Co-operative Education Advantages for Students Consideration for employment and grad school Improved technical skills Helps determine career path Excellent pay Advantages for Employers Recruiting Co-op students is more cost efficient Many students accept full time positions with their employer More diverse and dedicated students Students free up other engineers and bring in fresh approaches

252. 252 21.6 Co-operative Education Advantages for Schools Integrates theory and practice Keeps faculty informed of trends in industry Creates relationships between schools and businesses Improves a schools reputation Other Benefits Communication Skills Networking Self-discipline Management Experience Interactions with a variety of people

253. 253 21.7 Which is Best for You? Some Questions to help determine which is best for you Am I willing to sacrifice convenience for the best experience? How flexible can I be? How committed do I want to be? Seek out advice from professors, academic advisors, and campus placement officers

254. 254 Chapter 22 Connections: Liberal Arts and Engineering
