MEEG 3013 Name: __________________________________ (Underline your last name .) Test I ( ) ID#: _____________________________________ 1. (30%) At room temperature, a gap b = 0.02 in. exists between the aluminum rod A of 2-in. diameter ( 6 13.1 10 / F a α = ×° , 6 10.1 10 psi a E = × ) and the steel rod B of 1.5-in. diameter ( 6 6.5 10 / F s = , 6 29 10 psi s E = × ) as shown. If a tempera- ture rise of T occurs and the stress developed in the alumi- num rod is 4 ksi, a σ = − determine the value of . T 2. (30%) The horizontal shaft AD is attached to a fixed base at D and is subjected to the torques as shown, where 200 lb ft A T = and 1500 lb ft. B T = A 2-in.-diameter hole has been drilled into portion CD of the shaft. Knowing that the entire shaft is made of steel for which 6 11.2 10 psi G = × , determine the angle of twist A φ at end A . Fig. P2 Fig. P3 3. A fabric used in air-inflated structures is subjected to a biaxial loading that results in normal stresses x = 150 MPa and z = 180 MPa. The properties of the fabric can be approximated as E = 87 GPa and ν = 0.34. Circle on this test sheet
