Lecture
Stress, Strain, and Beams
Description
This lecture covers the concepts of stress, strain, and beams, starting with the definition of stress as the intensity of the force applied to a material per unit area. It then explains the relationship between force, area, and stress, as well as the elongation and contraction of materials under axial force. The lecture also delves into the deformation of bar networks and the calculation of deflection. Furthermore, it discusses the application of moments on internal sections, examples of beams on simple supports, and an example of a beam with alternating tensile and compressive fibers.
