No solid is perfectly rigid: forces stretch, shear and squeeze it. This chapter measures the deforming force as stress and the response as strain, follows a metal wire along its stress-strain curve from Hooke's law to fracture, defines the three elastic moduli (Young's, shear and bulk) with Poisson's ratio and stored elastic energy, and then uses them to size crane ropes, shape beams and estimate how tall a mountain can be.
