Learning Goal: To determine design factors of a rigid structure based on normal stress, shear stress, bearing stress, and embedment length. As shown, a mass of weight W is suspended from one end of the control arm ABC. Two brackets support the bearing pin at point B (i.e., the pin is subjected to double shear). The connection at point C is rigid and only experiences a horizontal force component. Let a = 1.0 m, b = 6.0 m, d = 240 mm, d2 = 110 mm, and W = 5.0 kN. W B D To determine the original length of a slender rod given the normal strain and deformation experienced by the rod due to an applied axial load. As shown, rod AB is subjected to the loading of two blocks, each of weight W (and where we neglect the mass of the pulley). The loading creates a normal strain in the rod given by = 0.035z1/2, where z is measured in centimeters. This strain corresponds to the total deformation in the rod given by AB = 4.80cm. B Z A W W L
