Which term describes force directed parallel to a surface?

Explanation:
Force directed parallel to a surface is called shear. It describes the load component that makes one part of a material slide past another along the plane of the surface. This is a common way structures fail when forces try to move across cross-sections or joints. The other terms don’t fit this idea: a pulling force refers to tension along a member, and seal or tile are not forces describing loading directions.
