AThe amount of deformation
BThe original unstretched length
CThe force that was applied
DThe area under the applied load
Answer & Solution
Correct answer: A. The amount of deformation
1. Hooke's law relates the force applied to an object and the change in its length.
2. That change in length is the amount of deformation the object has undergone.
3. The law makes the applied force proportional to that deformation.
4. The constant linking them depends on the object's shape, its material and the direction of the force.
