This lecture covers the concepts of stresses and strains in beams under pure bending, exploring the relative deformations and internal forces. Topics include the neutral axis, normal stress, moment of inertia, and maximum normal stress. The lecture also delves into finding the neutral axis, calculating relative deformations, and determining the maximum normal stress in beams. Additionally, it discusses the relationship between stress and moment of flexion through the moment of inertia, as well as calculating the moment of inertia for beams with simple section assemblies. The lecture concludes with examples illustrating the calculation of the neutral axis and moment of inertia for complex beam sections.
