Stress State Analysis: Shear Stress and Main Axes

This lecture covers the analysis of stress states in the plane, focusing on shear stress axes, maximum and minimum shear stresses, and main constraints. Examples are provided to determine the main axes, shear stresses, and normal stresses. The equivalent von Mise stress is calculated to assess safety factors. The lecture also discusses the safe region for stress states in the plane and the criteria for failure. Additionally, torsion in circular and non-circular bars, power transmission through shafts, and maximum power transmission capacity of hollow shafts are explored.
