1) A steel cable 1.25 inches in diameter and 50 ft long is to lift a 40,000 lb weight. What is the length of the cable during lifting? The modulus of elasticity of the steel is 30 x 106 psi. 2) A large flat plate is subjected to constant amplitude uniaxial cyclic tensile and compressive stresses. Compute the critical crack length if the fatigue life must be at least 3 x 106 cycles. Assume the initial maximum edge surface crack length to be 1.1 mm, and a maximum tensile stress of 160 MPa. Assume m=3.0, A=1.4 x 10-13 MPa in meter units, and Y=1.2. 3) Using the attached figure, for a Cu-20% Wt Ag alloy, determine the phases present, their percentage amounts, and their compositions at
