The extruded plastic shape will be subjected to an internal shear force of V = 270 lb. Dimensions of the cross section are b = 1.6 in., dr 3.2 in., c = 2.2 in., and t = 0.20 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 = 1.1 in. below the z centroidal axis. (c) the magnitude of the maximum horizontal shear stress in the extrusion. у (typ.) A B d z ус V b Answer: (a) TA= i psi = TB i psi (b) TC i psi (c) Tmax i psi
