PROBLEM 2.C4 Bar AB has a length L and is made of two different materials of given cross-sectional area, modulus of elasticity, and yield strength. The bar is subjected as shown to a load P that is gradually increased from zero until the deformation of the bar has reached a maximum value and then decreased back to zero. (a) Write a computer program that, for each of 25 values of equally spaced over a range extending from 0 to a value equal to 120% of the deformation causing both materials to yield, can be used to determine the maximum value of the load, the maximum normal stress in each material, the permanent deformation of the bar, and the residual stress in each material. (b) Use this program to solve Probs. 2.111 and 2.112.
