Torsion and Stress Concentration

This lecture covers topics such as torsional stress concentration, torsion of a non-circular member, and inelastic torsion. It explains the maximum shear stress in torsion, stress concentration factors, power transmission by a shaft, and torsion of different geometries. The lecture also discusses the torsion of rectangular bars and inelastic circular members, including the torsional stiffness and ultimate torque calculations.
