Torsion of Axisymmetric Cross Sections

This lecture covers the analysis of members under pure torsion, including torsional deformations, shear stresses, angle of twist, and failure surfaces. It explains the behavior of circular bars subjected to torsion, the concept of polar moment of inertia, and the torsion formula. The instructor discusses the shear strains and stresses within the bar, the implications of circular tubes, and the angle of twist in linearly elastic materials.
