The extruded plastic shape will be subjected to an internal shear force of V = 395 lb. Dimensions of the cross section are b = 1.0 in., d = 2.0 in., C= 1.4 in., and t= 0.10 in. Determine: (a) the magnitude of the horizontal shear stress at points A and B. (b) the magnitude of the horizontal shear stress at point C, which is located at a distance of yc = 0.7 in. below the z centroidal axis. (c) the magnitude of the maximum horizontal shear stress in the extrusion.
