What is the term for a change in the shape of a material caused by stress?

• A. Elasticity
• B. Deformation
• C. Compression
• D. Tension

Answer: (B)

The term for a change in the shape of a material caused by stress is deformation. This concept encompasses any alteration in the form or dimensions of a material resulting from an applied force or stress. Deformation can occur in various ways, such as stretching, compressing, or bending, depending on the type of stress applied. Elasticity, while related, refers specifically to a material's ability to return to its original shape after the stress is removed. Compression and tension are specific types of stress that can cause deformation: compression refers to a squeezing force, while tension involves stretching force. However, the broadest term that captures all these scenarios of shape change is deformation. Thus, deformation is the correct term to describe the overall change in shape due to stress on a material.
