shear and bending moment

Shear and bending moment are key concepts in structural engineering that describe how forces affect structures like beams. Shear forces occur when loads are applied sideways, attempting to slide one part of a structure past another. Bending moment, on the other hand, is the result of forces causing a beam to bend or curve. Together, they help engineers determine whether a structure can safely support its intended loads without failing. Understanding these principles is crucial for designing safe and effective buildings, bridges, and other structures.
