A beam may have zero shear stress at a section but may not have zero deflection; Hence, bending is primarily caused by bending moment In Torsion loading a stress element in a circular rod is subject to shear state The principal plane and the plane on which the shear stresses are maximum, they make 90 degree angle between them. If the Torque on a steel circular shaft (G=80 GPa) is 13.3 kN-m and the allowable shear stress is 98 MPa,...

G) Calculate the maximum bending stress that occurs in the beam.
Identify where it occurs (both with respect to its length and its
cross section) and indicate whether it is in tension or
compression. Compare this to the allowable stress for the material.
