1.

Hooke’s law states that, up to the limit of proportionality,

extension is proportional to the applied force
stress is proportional to area
force is proportional to length
strain is constant
2.

A spring extends by 0.040 m under a load of 6.0 N. What is its spring constant?

0.24 N m⁻¹
24 N m⁻¹
150 N m⁻¹
0.0067 N m⁻¹
3.

Stress is defined as

extension per unit length
force per unit extension
force per unit cross-sectional area
energy per unit volume
4.

Strain is

force divided by area
stress divided by extension
extension divided by original length
original length divided by extension
5.

The Young modulus of a material is

strain divided by stress
force divided by extension
stress divided by strain within the limit of proportionality
stress multiplied by strain
6.

1.0 × 10⁸ Pa
2.0 × 10¹¹ Pa
5.0 × 10¹⁰ Pa
2.0 × 10⁸ Pa
7.

The area under a force–extension graph represents

the Young modulus

9.

A material deforms plastically when

it obeys Hooke’s law
its extension is proportional to the load
it returns to its original shape
it does not return to its original length when the load is removed
