Answer 2

Answer:

There are three types of stress: compression, tension, and shear. Stress can cause strain, if it is sufficient to overcome the strength of the object that is under stress. Strain is a change in shape or size resulting from applied forces (deformation). Rocks only strain when placed under stress.

Note that strain is a dimensionless unit since it is the ratio of two lengths. But it is also common practice to state it as the ratio of two length units - like m/m or in/in.
