6. The figure (next page) shows an experimental set-up for testing the bending capacity of a wood cross-beam. Note that the grain directions for the two support columns are different. The vertical columns have a cross-section of 3 in. x 3 in., and are both 5 in. long. The beam has a cross-section of 2 in. x 4 in. and has a length of 8 in. The stronger column has a compressive strength of 4675 psi and a modulus of elasticity of 0.8 x 106 psi. The weaker column has a compressive strength of 1545 psi and a modulus of 0.4 x 106 psi. a. What is the maximum allowable load, P, on the beam if its modulus of rupture (MOR) is 5230 psi and the moment M=2P? b. If a total load P= 28000 lb is supported, wil either column fail due to this load? Show calculations to support your answer.

A rectangular steel block is 75 mm in the x-direction, 50 mm in the y-direction and 100 mm in the z direction. The block is subjected to triaxial loading consisting of three uniformly forces as follows: 24 KN tension in the x-direction, 250 KN compression in the y-direction, and 240 KN tension in the z-direction. If u = 0.3 and E = 200 GPa, Determine the total resulting strain in the z- direction. Note: CN is the last 2 non zero digits of your cellphone number

SITUATION 1. A composite bar is made by attaching a copper rod of length 900 mm and diameter 30 mm and a brass rod of length 600 mm and diameter 45 mm as shown. A load of 20 kN is applied at 20°C. For copper, E = 120 GPa and a = 18 x 10-6/°C. For brass, E = 90 GPa and a = 20 x 10-6/°C. The temperature rises to 50°C. Copper 44.95 MPa 63.29 MPa 72.84 MPa 900 mm 40.70 MPa + What is the stress in the copper rod if the supports are unyielding? Brass - 20 kN 600 mm
