The density of a material must change when the material is subjected to A) shear forces. B) elongation forces. C) compression forces. D) none of the above.

Question

Quizplus · Accepted Answer

The density of a material changes when it is subjected to compression forces because density is defined as mass per unit volume. When a material is compressed, its volume decreases while its mass remains constant, leading to an increase in density. Shear and elongation forces may change the shape of the material but do not necessarily result in a change in volume, and thus may not always affect density.
