Question

CIT 253 Homework #2 Spring 2018 Problem 1: The assembly below will be used for each problem. Lengths, diameters, and materials are provided. If the temperature when this system was assembled was 74F, what would be the stress in each cylinder at a temperature of 40F? Problem 2: If the fixed support at D were removed and the temperature change did not occur, how far would point D move if a 400 lb tension load was applied at the center of each cylinder? (Hint: what sections would you break up the assembly into to find the Normal forces?) Problem 3: Based on the results from problem 2 and the sections specified in your solution, how much would the diameter of each section shrink from the loads applied? (Hint: Look at Poisson's ratio for each of the sections listed. 2014-T6 Aluminum 304 Stainless 86100 Bronze steel 12 in. 8 in Cl 4 in. 4 ft 6 ft 3 ft
