Engineering Practices Review

Things that engineers must accomplish in order to be successful when engineering a solution to a problem is called the

• Criteria

• Constraint

• Prototype

• Improvement

Things that prevent or limit an engineer from finding the solution to a problem

• Criteria

• Constraint

• Prototype

• Improvement

Which question would you ask yourself during the ASK step of the Engineering Design Process?

• What are some possible solutions to your problem?

• What is the problem you are trying to solve?

• How can I improve my design?

• Is my design working properly?

A person who designs, builds, or maintains engines, machines or public works is a(n) ______________.

• client

• designer

• engineer

• builder

________________ are limitations on the project such as budget, materials and time.

• prototype

• constraints

• client

• problems

Janet is trying to improve the design of her lunchbox. Choose the criteria that she WOULD NOT want.

• The lunchbox should be comfortable to carry for long periods

• The lunchbox should keep the food colder

• The lunchbox could use a special pocket for water bottles

• The lunchbox should have sharp corners and rough edges.

During the design process, engineers...SELECT TWO

• test solutions to design problems more than once

• don't waste time learning about other solutions

• don't try to improve others' solutions or their own solutions

• create more than one solution to the same problem

Engineers______designs because it's important to be sure a solution works.

• test
• do not try

• break

• google

How could you optimize a prototype?

• Test it in a variety of conditions

• Find materials that better meet the criteria and constraints of the project

• Perform many tests to ensure proper function

• All of the above

Joel designed a tool for picking up metal screws that fall while he works on his car. The tool picks up the screws but drops them before Joel can pull them out. Which design change should he try next?

• Make the tool heavier

• Make the handle longer

• Use a different type of tool on his car

• Attach a strong magnet to the end of the tool
