Problem #6 (20 points): A solid rectangular bar is used as a support piece between two pin & bracket connections (at A and B) and supports an axial compressive load P, as shown below. Each connection allows the bar to rotate freely about the z-axis but is fixed from rotation about the y-axis. The width of the bar is 30 mm but the height is unknown. Assume E 100 GPa and Sy = 270 MPa. = ул Z< 2 m P 30 mm h (a) Calculate the minimum height (h) of the bar to support a load of P = 100 kN. (b) How will this bar fail?

A long re Lai nine: wall is braced by wood shores set at an angle of 30° and supported by concrete thrust blocks, as shown in the first part of the figure. The shores are evenly spaced at 3 m apart. For analysis purposes, the wall and shores are idealized as shown in the second part of the figure. Note that the base of the wall and both ends of the shores are assumed to be pinned. The pressure of the soil against the wall is assumed to be triangularly distributed, and the resultant force acting on a 3-meter length of the walls is F = 190 kN. If each shore has a 150 mm X 150 mm square cross section, what is the compressive stress

A large precast concrete panel for a warehouse is raised using two sets of cables at two lift lines, as shown in the figure part a. Cable 1 has a length L1 = 22 Ft, cable 2 has a length L2= 10 ft, and the distance along the panel between lift points Band D is d = 14 ft (see figure part b). The total weight of the panel is W = 85 kips.

A small lab scale has a rigid L-shaped frame ABC consisting of a horizontal aim AB (length b = 30 cm) and a vertical arm BC (length c = 20 cm) pivoted at point B. The pivot is attached to the outer frame BCD that stands on a laboratory bench.
