Torsion of Non-Circular Bars

This lecture covers the introduction to torsion, relative stresses and strains, and the determination of internal torques for prismatic segments of non-circular bars. It also explains the angle of torsion for complete bars, the shear stress profile in concentric bars made of multiple materials, and the torsional stiffness of bars. Additionally, it discusses the torsion of composite bars composed of different materials, the relative shear strain, and the maximum shear stress in each material. The lecture concludes with examples demonstrating the application of the concepts discussed.
