Mechanical Engineering Department fall 2009 T.C. Yeditepe University Page 1 ME 246 Strength of Materials Homework # 2 1- The stress-strain diagram for a steel bar is shown in the figure. Determine approximately the modulus of elasticity, the proportional limit, the ultimate stress, and the modulus of resilience. If the bar is loaded until it is stressed to 450 Mpa, determine the amount of elastic strain recovery and the permanent set or strain in the bar when it is unloaded. 2- The pipe is supported by a pin at C and an A-36 steel guy wire AB. If the wire has a diameter of

Unformatted text preview: 0.2 in., determine how much it stretches when a distributed load of w = 100 lb/ft acts on pipe. The material remains plastic. Mechanical Engineering Department fall 2009 T.C. Yeditepe University Page 2 3-A shear spring made from two blocks of rubber each having a height h , width b, and thickness a. The blocks are bonded to three plates as shown. If the plates are rigid and the shear modulus of the rubber is G, determine the displacement of plate A if a vertical load P is applied to this plate. Assume that the displacement is small so that ....
