Deformation of Straight Beams

This lecture covers the deformation of straight beams, focusing on the concepts of deviated bending and compound bending. It explains how bending moments affect the normal stress and deflection of beams, and how to calculate normal stresses under different bending conditions. The lecture also discusses the neutral axis, internal forces, and the relationship between bending moments and shear forces. Additionally, it delves into the concept of principal moments of inertia and the calculation of the ellipse of inertia for different beam sections.
