UNIT-I Tension,Compression and Shear stress

What is the definition of stress in strength of materials?

• Force per unit area

• Force per unit volume

• Force per unit length

• Force per unit weight

What is the definition of strain in strength of materials?

• Change in length per unit length

• Change in area per unit area

• Change in volume per unit volume

• Change in weight per unit weight

What is the relationship between stress and strain in a linear elastic material?

• Stress is proportional to strain

• Stress is inversely proportional to strain

• Stress is equal to strain

• Stress is proportional to the square of strain

What is deformation?

• The change in shape or size of a body

• The change in volume of a body

• The change in weight of a body

• The change in density of a body

What is tensile stress?

• The stress that is applied along the axis of a material

• The stress that is applied perpendicular to the axis of a material

• The stress that is applied in a circular manner around the axis of a material

• The stress that is applied in a diagonal manner across the axis of a material

What is compressive stress?

• The stress that is applied perpendicular to the axis of a material

• The stress that is applied along the axis of a material

• The stress that is applied in a circular manner around the axis of a material

• The stress that is applied in a diagonal manner across the axis of a material
