Question

what is considered the heart of engineering?
o a calculation
o b problem solving
o c prototyping
o d brainstorming

question 7 (1 point)
when we squish, bend, break, stretch, or otherwise deform an object what we see as result is considered the...
o a stress
o b force
o c strain
o d scaffold

question 8 (1 point)
another name for a load. also considered a push or pull.
o a force
o b scalar
o c stress
o d strain

Explanation:

• For the first question, problem - solving is at the core of engineering as engineers identify, analyze, and solve problems.
• For the second question, when an object is deformed, the resulting change in shape or size is strain. Stress is the internal resistance per unit area to the applied force causing deformation. Force is what causes the deformation. Scaffold is not related to the deformation result.
• For the third question, a load can be thought of as a push or pull, which is another name for force. Scalar is a quantity with only magnitude, stress is the internal resistance per unit area, and strain is the deformation.

Answer:

• Question 6: B. problem solving
• Question 7: C. strain
• Question 8: A. force
