Answer:
force acting on a material that produces a strain. Stress is a force applied over an area and therefore has units of Force/area (like lb/in 2 ). Pressure is a stress where the forces act equally from all directions.
If stress is not equal from all directions then we say that the stress is a differential stress. Three kinds of differential stress occur.
Tensional stress (or extensional stress), which stretches rock;
Compressional stress, which squeezes rock; and
Shear stress, which result in slippage and translation.
