Stress and Strain

An object that is deformed by a force and returns to its original form when the force is removed is exhibiting the property of elasticity.

• True

• False

What does Hooke's Law state?

• Stress is equal to strain

• Stress is inversely proportional to strain

• Stress is not related to strain

• Stress is directly proportional to strain

What is the importance of stress and strain in engineering design?

• To increase material failure

• To ensure safety and integrity of materials

• To create chaos in designs

• To ignore structural stability

What happens in Elastic Deformation?

• The material returns to its original dimensions

• The material breaks

• The material deforms permanently

• The material becomes softer

What is the Ultimate Tensile Strength used for?

• To determine the maximum stress a material can endure before failure

What is strain in mechanics?

• The stiffness of a material

• The displacement between particles in a material

• The deformation in a material

• The force applied to a material

It refers to the force exerted over an area which causes a deformation in the Earth's crust.

• Stress

• Strain

It refers to the term which is used to describe the deformation resulted from the application of external force.
