A rigid bar of weight hangs from three equally spaced wires: two of steel and one of aluminum (see figure). The diameter of the wires is 1/8 in. Before they were loaded, all three wires had the same length. What temperature increase AT in all three wires will result in the entire load being carried by the steel wires? (Assume Es = 30 x 10 psi, as 6.5 x 10-6/°F, and a = 12 x 10-6/°F.)

A steel plate 5/16 in. thick is embedded in a horizontal concrete slab and is used to anchor a high-strength vertical cable as shown in the figure below. The diameter of the hole in the plate is 0.75-inches, the ultimate strength of the steel used is 36 ksi, and the ultimate bonding stress between the steel plate and concrete is 300 psi. The designers considered a factor of safety of 3.60 is desired when P = 2.5 kips. Address the following: (a) Identify three potential failure modes for the complete system. For each mode develop a sketch which idealizes the mode of failure. (b) If you where required choose dimensions for the plate ("a" and "b"), how would you size these dimensions? (c) For one of the failure modes identified above, perform an analysis to determine adequate plate dimensions ("a" and "b") to support the required load of 2.5 kips with the established factor of safety. in.

A lifeboat hangs from two ship’s davits, as shown in the figure. A pin of diameter d = 0.8 in. passes through each davit and supports two pulleys, one on each side of the davit. Cables attached to the lifeboat pass over the pulleys and wind around winches that raise and lower the lifeboat. The lower parts of the cables are vertical and the upper parts make an angle a αα = 15∘∘ with the horizontal. The allowable tensile force in each cable is 1800 lb, and the allowable shear stress in the pins is 4000 psi. If the lifeboat weighs 1500 lb, what is the maximum weight that should be carried in the lifeboat?
