In Figure P4.5, member (1) has
a cross-sectional area of 0.7 in.2 and a yield strength of 50 ksi.
Member (2) has a cross-sectional area of 1.8 in.2 and a yield
strength of 36 ksi. A factor of safety of 1.67 with respect to
yield is required for both members. Use dimensions of a = 60 in., b
= 28 in., c = 54 in., and d = 72 in. Determine the maximum
allowable load P that may be applied to the assembly. Report the
factors of safety for both members at the allowable load.

Four steel rods each with a cross-sectional area of 1in 2 are embedded in a 5-in diameter light aggregate concrete cylinder. The steel has a yield strength of 36000 psi and a modulus of elasticity of 30x10n6 psi. Assume a very strong interface between the steel and the concrete causes them to experience identical deflections. A rigid plate is placed over both ends of the cylinder and a compressive axial force of 100,000 lb is applied. The stress (psi) induced...
