3 Introduction What is Engineering?

4 Introduction Engineering is: “ The profession in which a knowledge of the mathematical and natural sciences gained by study, experience, and practice is applied with judgment to develop ways to use economically the materials and forces of nature for the benefit of mankind “ “ The application of science to the needs of humanity” “The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behavior under specific operating conditions; all as respects an intended function, economics of operation and safety to life and property” “Engineering is the discipline and profession of applying scientific knowledge and utilizing natural laws and physical resources in order to design and implement materials , structures, machines, devices, systems, and processes that realize a desired objective and meet specified criteria”

8 Mechanical Engineering and Our World
Mechanical engineering is an engineering discipline that involves the application of principles of physics for analysis, design, manufacturing, and maintenance of mechanical systems. Mechanical engineers use the core principles as well as other knowledge in the field to design and analyze motor vehicles, aircraft, heating and cooling system, watercraft, manufacturing plants, industrial equipment and machinery, robotics, medical devices and MORE!

9 Mechanical Engineering
Some core subjects in mechanical engineering are: Statics and dynamics Strength of materials Solid dynamics Instrumentation and measurement Thermodynamics, heat transfer, energy conversion, and HVAC Fluid mechanics, and fluid dynamics Mechanism design (including kinematics and dynamics) Manufacturing processes Hydraulics and pneumatics Engineering design Mechatronics and control theory Other A combination of these core subjects, leads to research in engineering: Creating solutions for humans needs!

10 Disciplines of Mechanical Engineering
Thermal Science: The discipline that encompasses: Thermodynamics Fluid mechanics Heat transfer

11 Disciplines of Mechanical Engineering
Dynamics Vibrations and Acoustics: Characterization of mechanical components, structures, systems and materials, to support product development, safety, weight minimization and component optimization for aerospace, automotive, electronics and general manufacturing.

12 Dynamics and vibrations

13 Dynamics and vibrations

19 Disciplines of Mechanical Engineering
Biomechanical Engineering: It deals with the development of fundamental and applied engineering knowledge related to biomechanical systems, and the application of engineering expertise towards the design and development of leading-edge technologies to help people with disabilities.

20 Disciplines of Mechanical Engineering
Energy Engineering Studies different types of energy (electrical, mechanical, fuel, …) to implement efficient systems that can be used Boom of Green Energy

21 Disciplines of Mechanical Engineering
Computer Aided Engineering Apply mathematical theories, computationally efficient algorithms, and other tools for modeling, design, and simulation of a wide range of engineering artifacts and processes. Some focus areas can be mechanical, micro/nano-mechanical, electro-mechanical, thermal, fluid, and other multi-disciplinary and multi-scale systems.

22 Simulation

23 Computer Aided Engineering

24 Conclusion Mechanical engineers are professional problem-solvers who strive to find practical solutions that will benefit people or society.

25 The drive from Oakland to Pinewood:
Brain teaser The drive from Oakland to Pinewood: I covered the uphill distance of 70 Km at 42 km per hour. The return journey from Pinewood to Oakland was downhill, and I managed to drive at 56 km per hour. What was my average speed for the entire journey?

26 Brain teaser Average speed = Total distance / Total time Total distance = 2 × 70km. Time for uphill journey (from Oakland to Pinewood) = 70 / 42 hours. Time for downhill journey (from Pinewood to Oakland) = 70 / 56 hours. Total time = (70 / 42) + (70 / 56) Average speed = Total distance / Total time = 48km per hour. The common mistake made in solving this problem is to assume the average speed to be the arithmetic mean, i.e., ( )/ 2 = 49 km per hour.
