Define stress and strain.

• Stress is the force applied to a material, while strain is the resulting deformation or change in shape of the material.

• Stress is the temperature applied to a material, while strain is the resulting color change of the material.

• Stress is the speed applied to a material, while strain is the resulting acceleration of the material.

• Stress is the pressure applied to a material, while strain is the resulting expansion of the material.

Explain the stress-strain curve.

• The stress-strain curve shows the relationship between temperature and strain.

• The stress-strain curve shows the relationship between stress and strain for a material, highlighting its mechanical behavior under loading.

• The stress-strain curve is used to measure electrical conductivity.

• The stress-strain curve is only applicable to liquids.

How does temperature affect stress and strain?

• Temperature affects stress and strain by altering the atomic and molecular structure of materials.

• Temperature decreases stress but increases strain

• Temperature increases stress but decreases strain

• Temperature has no impact on stress and strain

What is the formula for stress?

• stress = work / time

• stress = force / area

• stress = mass * acceleration

• stress = volume / area

What are the units of stress?

• Pascals (Pa) or pounds per square inch (psi)

• Meters

• Degrees

• Kilograms

Explain the difference between tensile stress and compressive stress.

• Tensile stress pulls materials apart, compressive stress pushes materials together.

• Tensile stress has no effect on materials, compressive stress is the only stress that matters.

• Tensile stress pushes materials together, compressive stress pulls materials apart.

• Tensile stress compresses materials, compressive stress stretches materials.
