Which of the following is a measure of the resistance of a material to deformation under load?

  1. Stress

  2. Strain

  3. Elasticity

  4. Plasticity


Correct Option: A
Explanation:

Stress is defined as the force per unit area acting on a material.

What is the ratio of the change in length to the original length of a material under stress?

  1. Stress

  2. Strain

  3. Elasticity

  4. Plasticity


Correct Option: B
Explanation:

Strain is defined as the ratio of the change in length to the original length of a material under stress.

Which of the following materials exhibits elastic behavior?

  1. Steel

  2. Rubber

  3. Concrete

  4. Glass


Correct Option: A
Explanation:

Steel is an elastic material, meaning that it returns to its original shape after the stress is removed.

Which of the following materials exhibits plastic behavior?

  1. Steel

  2. Rubber

  3. Concrete

  4. Glass


Correct Option: B
Explanation:

Rubber is a plastic material, meaning that it does not return to its original shape after the stress is removed.

What is the maximum stress that a material can withstand before it fails?

  1. Yield strength

  2. Tensile strength

  3. Compressive strength

  4. Shear strength


Correct Option: B
Explanation:

Tensile strength is the maximum stress that a material can withstand before it fails.

What is the ability of a material to absorb energy without fracturing?

  1. Toughness

  2. Hardness

  3. Strength

  4. Elasticity


Correct Option: A
Explanation:

Toughness is the ability of a material to absorb energy without fracturing.

Which of the following materials is the hardest?

  1. Diamond

  2. Sapphire

  3. Ruby
