Abstract: This chapter discusses the manner in which the loads are transmitted through structures, as internal forces, to the supports. Internal forces or stresses exist at every section of a loaded body, but they are not apparent to the senses. Wherever an internal force is severed, it will have to be replaced by a pair of equal and opposite forces acting on the cut faces, of such a value that the equilibrium of each portion of the structure is preserved. The axial force at any cross-section of a beam is the component of the internal force transmitted across the section that is parallel to the length of the member, and its line of action passes through the centroid of the cross-section. The shearing force at any cross-section of a beam is the component of the internal force transmitted across the section lying in the plane of the cross-section, that is, perpendicular to the length of the beam.
