Beam Bending: Theory and Applications

This lecture covers the theory and applications of beam bending, focusing on the moment-curvature relation, pure bending, general bending, and typical boundary conditions. It also delves into elasticity concepts such as stress fields, forces, and moments, as well as the kinematics of beams. The instructor explains the importance of small deflection approximation and the significance of shear forces in beam deformation. The lecture concludes with examples of cantilever beams under concentrated forces and the relationship between bending stiffness and curvature.
