Elasticity | MCQs

Explanation

Steel is more elastic than rubber because the ratio of stress to strain is more for steel.

This indicates that steel deforms less under the same amount of stress compared to rubber, making it more elastic.

Explanation

If a spring stretches easily, it means that it requires less force to stretch it a certain distance.

This is indicative of a spring with a small spring constant (k).

The spring constant is a measure of a spring's stiffness.

A smaller value means the spring is less stiff and more easily deformed.

Explanation

Steel is more elastic than rubber, glass, and wood.

Elasticity refers to the material's ability to return to its original shape after being deformed.

Steel has a higher modulus of elasticity (Young's modulus), meaning it can withstand greater stress and still return to its original shape.

Explanation

Price elasticity for various goods

• Normal goods- normal goods have a positive elasticity of supply as supplied quantity changes positively with the change in the price of the commodity.

• Inferior goods- Inferior goods have a negative price elasticity of supply as inferior goods have a negative relationship with the price of the commodity.

Explanation

strain and stress relationship is defined by Hooke's law.

This point of the ratio between the strain and stress is called the proportional limit.

The slope of the curve is referred to as the modulus of elasticity of Young's modulus.
