The pin-connected structure shown in the figure consists of two cold-rolled steel (E = 30,000 ksi) bars (1) and a bronze (E = 15,000 ksi) bar (2) that are connected at pin D. All three bars have cross-sectional areas of 0.375 in². A load of P = 11 kips is applied to the structure at pin D. Using a = 3 ft and b = 5 ft, calculate the downward displacement of pin D.

A rigid bar of weight W = 750 lb 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 T in all three wires will result in the entire load being carried by the steel wires? (Assume Es= 30 × 106 psi, as= 6.5 × 10-6 /'F, and aa= 12 × 10-6F.)
A pinned-end strut of aluminum (E = 10,400 ksi) with a length L = 6 ft is constructed of circular tubing with an outside diameter d = 1 in. (sec figure).

A sign for an automobile service station is supported by two aluminum poles of hollow circular cross section, as shown in the figure. The poles are being designed to resist a wind pressure of 75 lb/ft" against the full area of the sign. The dimensions of the poles and sign are hx= 20 ft, /r =5 ft, and h = 10 ft. To prevent buckling of the walls of the poles, the thickness e is specified as one-tenth the outside diameter d.

(b) Determine the minimum required diameter based upon an allowable shear stress of 300 psi.
The cross section of a column built up of two steel I-beams (S 150 × 25.7 sections) is shown in the figure.

The column is assumed to have pinned ends and may buckle in any direction. Assuming E = 200 GPa and L = 8.5 m, calculate the critical load PCIfor the column.
