NVM Diagrams: Quick Method for Straight Beams

This lecture covers the quick method for determining the shape of straight beams using NVM diagrams, including the effects of concentrated forces and moments, rules derived from differential equilibrium equations, and the relationship between distributed loads, shear forces, and bending moments. The instructor explains how to calculate NVM diagrams for uniformly loaded beams, emphasizing static conditions and cut-offs. Examples are provided to illustrate correct and incorrect NVM diagrams, with a focus on understanding the signs and directions of forces and moments.
