The Practices of Engineering

What would a limited amount of time to complete a project be considered?

• Criteria
• Constraint
• Cost
• All of the above

What is the main job of engineers?

• Working on a computer
• Using math
• Using science
• Solving problems

Which step might be included when defining the problem?

• Listing criteria and constraints
• Research
• Testing a prototype
• Brainstorming

An engineer is trying to design a phone case that can withstand a drop of 10 feet. Being able to withstand a drop of 10 feet would be a

• Criteria

• Constraint

An engineer is trying to design a phone case, but only has two months to do so. Having two months would be a

• Criteria

• Constraint

Engineers have been designing a ship that can move through large ocean waves safely. After research, they decide that new criteria and constraints will improve the design of the ship. Which action will they most likely take in dealing with the new criteria and constraints?

• A. Build the ship according to the original plan.

• B. Scrap the plan and start the design process again.

• C. Consider the constraints only and revise the design process.

• D. Reframe the criteria and constraints to match the additional research.

Wind turbines are used as a source of clean renewable energy in rural areas. Their design was changed because of public concerns about possible disruptions to everyday life. Which statement best describes the approach that was used to evaluate the design?

• A. It considered corporate needs.

• B. It considered the societal needs.

• C. It was mainly concerned about the effects on wildlife.

• D. It was mainly concerned with the efficiency of the turbines.
