Applied Materials Interview Questions and Answers

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

• Stress is the force applied to a material per unit area

• Strain is the measure of deformation or change in shape of a material

• Stress and strain are related by the material's modulus of elasticity

• Example: When a rubber band is stretched, it experiences stress which causes strain in the form of elongation
