A rigid bar ABCD is supported by two vertical steel rods (E-200GPa), each with a circular cross section of 20mm diameter. A 12kN force is applied at the end to rotate the rigid bar counterclockwise. L = 1200mm d = 20mm (1) 100mm Rigid bar y,v B Determine the following: a) Relationship between the deflections of the two rods b) Axial force in each rod c) Compressive stress in each rod d) Critical buckling load of each rod e) Safety factor with respect to buckling for each rod (2) X,U 40mm C d = 20mm L = 800mm 60mm D 12kN
