5. Two blocks of wood, 50 mm wide and 20 mm thick, are glued together as shown in the figure. (a) Using FBD concept, determine the shear load and from it the shearing stress in the glued joint if P 6000 N. (b) generalize the procedure of part (a) to show that the shearing stress on a plane inclined at an angle 0 to a transverse section of area A is Ss P sin 20/2A
