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: EAB= 2E, EBC= E, ECD= 3E, AAB= A, ABD= 2A. 2. The structure ABCis 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 0qat the support Oand zero at the free end B. The bar has constant Young’s modulus Eand cross sectional area A. (a)Calculate the elongation of the entire bar. (b)Calculate the displacement of point C(see figure below).
