The extruded plastic shape will be subjected to an internal shear force of V = 380 lb.  Dimensions of the cross section are b = 1.0 in., d = 2.0 in., c = 1.4 in., and t = 0.18 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.
