Compressive Stress is defined as which of the following?

Compressive Stress is defined as which of the following?

• A. Pulls and stretches the material.
• B. Pushes the material together.
• C. Breaks the material by sliding over surfaces.
• D. Causes bending.

Answer: (B)

Compressive stress is the internal force that pushes a material together, squeezing it and often shortening its length. That description matches forces that push the material together. The other ideas describe different effects: tensile stress is pulling and elongating, shear stress involves sliding across surfaces, and bending comes from a moment causing one side to compress while the other stretches.
