Problem 3: (M4) Your boss at a construction company asked you to verify the thickness of a 3 m long hollow-square steel column (E=200 GPA) that can withstand an axial compressive load of 50 MN, the outer dimension a is 400 mm. The column's cross section is shown in Figure.4. Assume the column is a fixed-free type. Figure.4: Cross-section of a hollow-square steel column
A steel [E = 200 GPa] bar (1) supports beam AB. The cross-sectional area of the bar is 660 mm2. If the stress in the bar must not exceed 290 MPa and the maximum deformation in the bar must not exceed 10 mm, determine the maximum load P that may be supported by this structure. Use dimensions of a = 7 m, b = 4.2 m, and c = 9.1 m.

The pin-connected structure shown in the figure consists of a rigid beam ABCD and two supporting bars. Bar (1) is a bronze alloy [E = 101 GPa] with a cross-sectional area of A₁ = 230 mm². Bar (2) is an aluminum alloy [E = 71 GPa] with a cross-sectional area of A₂ = 740 mm². All bars are unstressed before the load P is applied; however, there is a 4-mm clearance in the pin connection at A. Assume L₁ = 2040 mm, a = 1020 mm, b = 630 mm, c = 460 mm, and L₂ = 1470 mm.
