When an object is in equilibrium under the action of three forces which are not parallel, then the three forces must be concurrent.
Equilibrium of Rigid Bodies
Subject and UNIT: Engineering Mechanics: Unit II: Equilibrium of Rigid Bodies
When objects are supported by some supporting mechanisms, the supporting mechanism exerts a force or couple moment on the object which tries to restrict the motion of the object.
