Question

An engineer decides to use a slightly weaker material rather than a stronger material, since she knows that the stronger material can break suddenly. This is an example of what?

a choosing a material that will show warning before it fails

b using composite materials that combine strength

c using a material for multiple applications

d using design techniques that increase efficiency and reduce cost

Answer 1

its... choosing a material that will show warning before it fails.

Step-by-step explanation:

Answer 2

Answer: Option (d) is the correct answer.

Step-by-step explanation:

Since the engineer has used slightly weaker material, therefore, it is obvious that cost price of material will be low as it is a weak material.

Also, it will help the engineer to use suitable design techniques in order to increase the efficiency. On the other hand, cost of object or device made by engineer will also reduce since weaker materials are used.

Thus, we can conclude that out of the given options, this is an example of using design techniques that increase efficiency and reduce cost.
