Question

According to Hooke's law of elasticity, if stress is increased, the ratio of stress to strain


A
decreases
loader
B
increases
loader
C
becomes zero
loader
D
remains constant
loader

Solution

The correct option is D remains constant
According to Hooke's law, within the elastic limit, stress is directly proportional to the strain:
 i.e., $$stress \propto strain$$
or $$Stress=k \times strain$$
$$\cfrac { stress }{ strain } =k\quad $$
where $$k$$ is the proportionality constant and is known as modulus of elasticity.
