Static I: Beam Diagrams

This lecture covers the deduction of beam diagrams for straight beams, the effect of concentrated forces or moments on the diagrams, the determination of values at beam ends, and the drawing rules. It also explains the rules derived from equilibrium differential equations, discontinuities in the diagrams, and the relationship between distributed load and normal force, shear force, and bending moment. Examples are provided to illustrate the quick method for calculating beam diagrams. The lecture also discusses the signs of beam diagrams, the use of a butterfly symbol, and the correct representation of diagrams. The instructor emphasizes the importance of correctly representing the signs and sides of the diagrams.
