Question

According to Hook's law of elasticity, within the elastic limit, if stress is increased, then the ratio of stress to strain

• A. becomes zero
• B. remains constant
• C. decreases
• D. increases

Answer 1

The correct option is B remains constant

According to Hook's law of elasticity, within the elastic limit stress is proportional to the strain.
$\therefore$The ratio of stress to strain is always constant. If stress is increased, strain will also increase so that their ratio remains constant.
