P9.17 The extruded plastic shape shown in Figure P9.17 will be subjected to an internal shear force V = 300 lb. The dimensions of the cross section are b = 1.5 in., d = 3.0 in., c = 2.0 in., and t = 0.15 in. Determine (a) the horizontal shear stress at points A and B. (b) the horizontal shear stress at point C, which is located at a distance yc = 1.0 in. below the z centroidal axis. (c) the maximum horizontal shear stress in the extrusion. ус B b V (typ.) d FIGURE P9.17 P9.17 The extruded plastic shape shown in Figure P9.17 will be subjected to an internal shear force V = 300 lb.
