The EDP

Match the following

• Making a test model that contains only the important design features.

• Prototype

• To share information with others, discuss.

• Communicate

• To make a revision or change to your original design.

• Test

• Seeing if the solution works.

• Redesign

You begin to create a prototype of your design only to find that your solution isn't working at all. What should you do?

• Add more tape

• Go back to an earlier stage and choose another solution

• Blame your resources and give up

• Keep going and hope it is still better than other peoples

Answer explanation

Forcing yourself to continue working on a failed idea is a waste of one of our most precious resources, TIME.

As we develop solutions we expect to fail are run into problems, this is why engineers are good at keeping records. This way we can easily go back and take a different route on our wat to eventual success.

What two things determine whether or not engineering solutions are successful?

• If it stays within the constraints

• If it looks cool

• If it solves a problem

• If it meets the criteria

When finding the solution to an engineering problem, there is/are usually 

• only one possible correct solution
• a very limited number of possible correct solutions
• many possible correct solutions

Answer explanation

Just like we have many different types of light bulbs, we can have many different solutions to any design problem.

You try, you fail

you try, you fail

you try, you fail

It's OK if you fail as long as you keep doing this step in the engineering design process...

• Think about why you failed

• Quit

• Improve upon failure points

• Create a new problem

When a customer gives you a list of must-have features for a new machine design, those are the _______ for your design.

• options

• criteria

• roadblocks

• challenges

Answer explanation

Criteria are the standards by which your design will be judged by the consumer.

Which of the following features can be a constraint to an engineering project?

• A safety belt for an operator

• An enclosed operator cabin

• A high-cost material option

• A scratch resistant coating

Answer explanation

A constraint is a limitation or restriction such as budget that doesn't allow for expensive materials.

In engineering, a balance achieved between two desirable but incompatible features, is called a:

Answer explanation

A trade-off is a happy medium, when you cannot have everything you really want in a design.

At the start of a new project, we have to __________ the problem.

• draw

• distract

• disclose

• define

Answer explanation

You are writing a statement explaining what the purpose of the project is. Defining the problem does not mean to think about all the things that could go wrong.

What is a process?

• The end result of following a set of directions

• A series of actions or steps taken in order to achieve a particular end.
• Something that happens spontaneously or accidently

• A list of things that you need to get done today

Answer explanation

When you math teacher says "Show your work", she wants to see the individual steps on how you came to the end solution.
