12.4 Elasticity and Plasticity
Where the proportional limit ends reversible deformation, the permanent set beyond it, and fracture points read off a stress-strain curve.

12.4 Exercise 2
Note: Unless stated otherwise, the weights of the wires, rods, and other elements are assumed to be negligible. Elastic moduli of selected materials are given in the reference.
Steel rods are commonly placed in concrete before it sets. What is the purpose of these rods?
12.4 Exercise 10
Two thin rods, one made of steel and the other of aluminum, are joined end to end. Each rod is 2.0 m long and has cross-sectional area If a 10,000-N tensile force is applied at each end of the combination, find: (a) stress in each rod; (b) strain in each rod; and, (c) elongation of each rod.
