alleryThe magnitude of stress is the applied normal force divided by what?
AThe length
BThe area
CThe volume
DThe density
Answer & Solution
Correct answer: B. The area
1. Stress measures how concentrated the deforming force is.
2. The same force spread over a wider face produces less stress.
3. So the magnitude of the stress is the force divided by the area.
