1. Use the maximum shear stress value obtained for the cross sectional areas in torsion and angle of twist, to find maximum moment for certain cross section beam subjected to pure bending (flexure formula): Given torque: (4-8 kN.m) (a= cm), (R= Rectangular), (C=Circular) cross sections 2. Apply the maximum shear in the flexure formula, to obtain maximum moment in the beam.
