Question

question: which of the following has uniform stress? answer options: select one of four lithostatic pressure shear stress compression tension

Explanation:

Lithostatic pressure (also called hydrostatic pressure in some contexts, but lithostatic for rock - like materials) is the pressure exerted by the weight of overlying rock or fluid columns. It acts uniformly in all directions (isotropic) on a given point within the material, meaning the stress is uniform. Shear stress involves forces parallel to a plane, compression is a type of stress that shortens a material (and can be non - uniform depending on the situation), and tension is a stress that stretches a material (also can be non - uniform). So among the options, lithostatic pressure has uniform stress.

Answer:

A. Lithostatic pressure
