Stress and Strain Quiz

What is the stress-strain relationship?

• The stress-strain relationship is the relationship between pressure and strain in a material.

• The stress-strain relationship is the relationship between temperature and strain in a material.

• The stress-strain relationship describes the relationship between stress and strain in a material.

• The stress-strain relationship is the relationship between density and strain in a material.

What is shear stress?

• Force per unit volume acting perpendicular to the surface of a material

• Force per unit volume acting parallel to the surface of a material

• Force per unit area acting parallel to the surface of a material

• Force per unit area acting perpendicular to the surface of a material

Which type of stress occurs when an object is being compressed or squeezed?

• shear stress

• tensile stress

• thermal stress

• compressive stress

Which type of stress occurs when an object is being stretched or pulled?

• shear stress

• bending stress

• compressive stress

• tensile stress

What is the formula to calculate strain?

• Strain = Change in length + Original length

• Strain = Change in length / Original length

• Strain = Change in length * Original length

• Strain = Change in length / Final length

What is the unit of strain?

• dimensionless

• meter

• kilogram

• second

Tensile stress in the rod hangers is the result of:
