In the mechanics of materials, the strength of a material is its ability to withstand an applied load without failure or plastic deformation. The field of strength of materials deals with forces and deformations that result from their acting on a material. A load applied to a mechanical member will induce internal forces within the member called stresses when those forces are expressed on … Webmechanical instability: A measurable alteration of joint opening due to disruption of one or more of the joint’s mechanical stabilisers (e.g., the capsule, tendons, muscles or bones).

An important property of systems at mechanical equilibrium is their stability. Potential energy stability test If we have a function which describes the system's potential energy, we can determine the system's equilibria using calculus. A system is in mechanical equilibrium at the critical points of the function … See more In classical mechanics, a particle is in mechanical equilibrium if the net force on that particle is zero. By extension, a physical system made up of many parts is in mechanical equilibrium if the net force on each of its … See more A stationary object (or set of objects) is in "static equilibrium," which is a special case of mechanical equilibrium.
