Engineering Design Process

​Engineering Design Process

Multiple Choice

A group of engineers is designing a bridge to span a river. They have come up with three different designs, each with its own set of strengths and weaknesses. They will choose the design that best meets their criteria and constraints. The characteristics of each design are summarized in the table below. Which design would be the best choice based on the criteria and constraints provided?

• Design A

• Design B

• Design C

Explanation

The table provides information on the strengths, weaknesses, and cost of each design option. The best choice based on the criteria and constraints provided would be Design B because it is the least expensive option, and it can be built quickly, which is important because of the time constraints. Design B may not be as durable as the other options, and it has a limited weight capacity, but these weaknesses are outweighed by the other strengths and the constraints. Therefore, answer choice B, Design B, is the best choice.

Multiple Choice

A group of engineers is designing a new car that runs on electricity. They have come up with three different designs, each with its own set of strengths and weaknesses. They will choose the design that best meets their criteria and constraints. The table below summarizes the characteristics of each design option. Which design would be the best choice based on the criteria and constraints provided?

• Design A

• Design B

• Design C

Multiple Choice

A group of engineers is designing a new water bottle that is reusable and eco-friendly. They have come up with three different designs, each with its own set of strengths and weaknesses. They will choose the design that best meets their criteria and constraints. The table below summarizes the characteristics of each design option. Which design would be the best choice based on the criteria and constraints provided?

• Design A

• Design B

• Design C

Explanation

The table provides information on the strengths, weaknesses, and cost of each design option. The best choice based on the criteria and constraints provided would be Design C because it is made from biodegradable materials, easy to clean, and moderately priced. Although it is not very durable, this weakness is outweighed by the other strengths and the constraints. Therefore, answer choice C, Design C, is the best choice.
