The pinned truss in Fig Q2 is subject to a vertical load of 120kN at Pin C. The strut members AB, BC and AC each have cross-sectional diameters of 50mm, 25mm and 25mm respectively. The struts are made from Steel having a Young's Modulus of 210GPA and yield strength of 350MPA. Calculate: a) the axial stress in each member b) the stability of the structure against buckling (stating which strut is likely to buckle) c) the diameter of the shear pin at A, given it is acting in double shear and should be based upon von Mises' shear strength criterion and a Safety factor of 1.5.

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 horizontal rigid bar ABC is pinned at end A and supported by two cables at points B and C. A vertical load P = 10 kN acts at end C of the bar. The two cables are made of steel with a modulus elasticity E = 200 GPa and have the same cross-sectional area.

A horizontal rigid bar of weight If' = 72001b is supported by three slender circular rods that are equally spaced (see Figure)'.
