TEACHER INFORMATION

TARGET AUDIENCE High School students (grades 9-12) that are interested in Engineering and the mechanical arts. Students open to learn about new things

SO WHAT IS ENGINEERING ANYWAY? Engineering is defined as “The branch of science and technology concerned with the design, building, and use of engines, machines, and structures. Engineering really is so much more than that! Engineering was involved in everything from this computer to the shoes you are wearing and the packaging they came in! Back Next Home

WELL IF THAT IS ENGINEERING, WHAT IS TECHNOLOGY? Technology is defined as the application of scientific knowledge for practical purposes. When people think of technology they typically think of computers, phones, and other electronics. This is also a misconception. Technology is any tool created for practical purposes. This can be anything from a pencil to the design of your chair! Back Next Home

DRAFTING What is drafting? The systematic representation and dimensional specification of mechanical and architectural structures or designs Drafting is used to prepare a preliminary version of something It is used to fully express the details within a technical drawing. Back Next Home

TYPES OF DRAFTING Three view Generally dimensioned and shows detail The complete shape of the object should be know by looking at this drawing alone Back Next Home

TYPES OF DRAFTING Isometric View This is the same object in isometric, or 3D view. It is generally used to simply show what the final object will look like It is hard to dimension or show a lot of important details in this view Back Next Home

DIFFERENT LINE TYPES Solid line This line is used to show an edge in some fashion Hidden (dashed) line A hidden line is used to show a feature behind a solid surface Center line The center line is used to show the center of a circle or a curved surface Back Next Home

YOU’VE TALKED ABOUT DIMENSIONING, SO WHAT IS IT? Dimensioning is to mark up a drawing or sketch with measurements This is used to convey specific information such as the size and location of the circle on this drawing to the right. Back Next Home

APPLICATION QUESTION Which line represents a hidden feature? A. B. C. Back Next Home

B. Is correct! This is called a hidden line (or dashed line) and it shows a feature that is hidden behind another! This is the end of the section, return to the home screen to choose a new one Back Next Home

What is a prototype? A prototype is the original form or a preliminary version of something It is not a finished product but almost a working model of the original sketches It is an experimental model of whatever it is that you are designing PROTOTYPING Back Next Home

WHY PROTOTYPE?! Prototyping is a cheap way to create a project or at least a preliminary representation of what the project will look like or how it will perform Prototyping saves money because it can point out potential flaws in the design earlier A prototype can also be used to present a product in order to raise money to create an actual version of it. Back Next Home

BENEFITS OF PROTOTYPING Your prototype will be cheaper A prototype can be thrown together much faster than a final product A prototype is not meant to last but to show weak points in a Back Next Home

APPLICATION QUESTION At what stage is prototyping used? A.At the beginning of a project, after brainstorming B.When a design is ready to be first tested C.When the product needs to be first presented D.All of the above Back Next Home

D. ALL OF THE ABOVE Is correct! Prototyping can be done at virtually any stage in development depending on whether or not you need to test it for possible weaknesses or even present it! Back Next Home This is the end of the section, return to the home screen to choose a new one

PRODUCT DESIGN How is a design started? A product is designed due to customer demand or A product is designed as a side project Back Next Home

PROJECTS ARE NOT EASY Many times the customer is not happy with the product because it wasn’t made exactly how they wanted it, but they didn’t specify what they wanted close enough That is why it is important to ask many questions before you start a project to be sure it will be exactly to specifications Back Next Home

Some products are very much trial and error and several were turned down upon first being presented. HOW TODAY’S PRODUCTS WERE CREATED Did glue used in sticky notes was a huge failure? It was supposed to be a strong glue and was later put on paper and found that it could be easily removed. It was still turned down when it was presented but was later accepted when it was seen being used around the office and made millions. Back Next Home

APPLICATION QUESTION Is a design that does not meet customer needs usually the engineers fault? A.Yes, the engineer should know what the customer wanted B.No, the customer should have been more specific Back Next Home

A. YES, THE ENGINEER SHOULD HAVE KNOWN WHAT THE CUSTOMER WANTED Is correct! Even if the customer wasn’t specific enough, it is the job of an engineer to find out exactly what they want even when the customer doesn’t know exactly what it is! The customer is always right!

QUIZ TIME! You will no longer be able to use the next and back buttons, however there will still be a home button. Click to begin! Home

AWW TRY AGAIN! For this one make sure you read all of the answers before you choose one, but I know you can do it! You just have to Try again!! Home Review material?

Why is Prototyping important? A.To point out potential flaws B.To save money C.To present a product early D.All of the above Home QUESTION 1

D. ALL OF THE ABOVE Is correct! Prototyping is used to point out potential flaws in the design, save money on expensive parts, and present a product, or its representation, early to a group. Next Question Home

QUESTION 2 Upon first being presented, how successful was the sticky note? Home A.A huge success! B.They barely accepted it C.It was turned down

C. IT WAS TURNED DOWN! Is correct! Crazy to think such a widely used object such as the sticky note was not only turned down, but was created because of a failure. Cool huh? Next Question Home

QUESTION 3 What Should the red line be? Home A.Solid line B.Center line C.Hidden line

A. SOLID LINE Is correct! The red line is representing a visible edge Next Question Home

QUESTION 4 Home What Should the red line be? A.Solid line B.Center line C.Hidden line

C. HIDDEN LINE Is correct! Simply moving that one view changes everything! Now that red line is behind a solid surface and should be represented with a hidden (or dashed) line. Next Question Home

QUESTION 5 Home Which type of drafting generally has dimensions on it? A.Three view B.Isometric C.Neither

QUESTION 6 Home What is a dimension? (in engineering drawings) A.The heading and any extra information available B.The orientation of the drawing C.The measurements on a drawing D.All of the above

C. THE MEASUREMENTS ON A DRAWING Is correct! A dimension is the measurement shown on a drawing Next Question Home

QUESTION 7 How complete should dimensioning be on a three view drawing? Home A.Very basic, it is just a representation B.A little detailed, they should get the general idea C.Fully detailed, you should be able to recreate the shape off of the drawing alone D.All of the above, any would do just fine

C. FULLY DETAILED, YOU SHOULD BE ABLE TO RECREATE THE SHAPE OFF OF THE DRAWING ALONE Is correct! Though it is harder for some detailed objects, you should be able to replicate the shape of an object by its dimensioned technical drawing alone. Next Question Home

QUESTION 8 Are products always used for what they’re intended purpose was for? Home A.Yes, when a product is created it is always used for its intended purpose B.No, customers use products for things different from their intended purposes all the time

B. NO Is correct! Products are misused or simply used for different purposes all the time, which is why it is so important that we think out our designs fully to make sure they are safe for whatever they are used for! Next Question Home
