EM 319 Mechanics of Solids Fall 2010 Homework #2 Due: 9/9/2010 1. Find the change of length of the entire structure, given that: E AB = 2 E , E BC = E , E CD = 3 E , A AB = A , A BD = 2 A . 2. The structure ABC is subjected to the loads shown in the figure. The member has constant thickness t (out-of plane direction) and Young’s modulus of the material is E . Find the change of length of the structure. 3. A bar is subjected to linearly distributed load which has intensity 0 q at the support O and zero at the free end B . The bar has constant Young’s modulus E and cross sectional area A . (a) Calculate the elongation of the entire bar. (b) Calculate the displacement of point C (see figure below).
