Stress - Strain Revision

The change in length (or area) of a body due to the application of tensile stress gives

• Stress-Strain Curve

• Tensile Strain

• Tensile Stress

• None of the option

Force applied per unit area gives

• Stress

• Strain

• Deformation

• None of the option

What is the deformation of materials in response to stress?

• Stress

• Strain

• Elastic Deformation

• Plastic Deformation

• Fault

What is the process when stress causes a material to strain, but afterward the material returns to its original shape?

• Stress

• Strain

• Elastic Deformation

• Plastic Deformation

• Fault

Deformation

• the process by which the shape of a rock changes because of stress

• the amount of force per square unit area on a given material

• stress that occurs when an object is stretched

• stress that occurs when an object is squeezed

The unit of stress is :

• N/m²

• W/m²

• N/m⁴

• T/m²

Stress is given by:

• σ=2F/A

• σ=FA

• σ=F/A

• None of the option

State of stress in which a material is being pulled apart.

• Tension
• Compression
• Torsion
• Bending

Refers to the twisting of a structural member that is loaded by couples (torque) that produce rotation about the member's longitudinal axis.

• Torsion
• Compression
• Tension
• Bending

Strength of the material at rupture. This is also known as the breaking strength.

• Rapture Strength
• Proportional Limit
• Elastic Limit
• Yield Point
• Ultimate strength
