Lecture Goals. Internal Force in StructuresAxial LoadTorqueShear Forces Bending Moment . What use are the Internal Loads?. In terms of the grand scheme of things, why do we need to find the internal loads?Stresses are determined by the bending moment and shear stresses are determined by the maximum shear force and the maximum torsional moments.NOT ALL MAXIMUM FORCES OCCUR AT TH SUPPORTS! .
