4.2: Stresses in Beams - Engineering LibreTexts

WebbSomething that is elastic can be stretched or deformed (changed) and returned to its original form, like a rubber band. It tries to come back to its first shape. The stress is the force applied; the strain is how much the shape is changed, and the elastic modulus is the ratio between those numbers.. This idea was first suggested by Robert Hooke in 1675. http://www.annualreport.psg.fr/OUC_theory-of-unsymmetrical-bending-of-beams.pdf
