Theorem: If a structure is in equilibrium, then, each part of the structure is in equilibrium. V D N D M D a N D , V D , and M D are the internal resisting forces (positive direction is shown) b N D = Normal force = the sum of all longitudinal (Axial) forces [including reactions] acting to the left or to the right of the cut. c V D = Shear force = the sum of all transverse forces [including reactions] acting to the left or to the right of the cut. d M D = Bending moment = the sum of moments about D of all forces [including reactions] acting to the left or to the right of the.
