The screw clamp shown in the figure applies a P = 500 N pressing force to the wooden blocks between the jaws. In this case; a) calculate the greatest tensile and compressive stresses occurring in section a-a shown in the figure, b) show (draw) the distribution of normal stresses along the section height, c) clamp material tensile safe stress em. Since = 50MPa and compressive stress em = 80MPa, what is the largest compressive load (P) that can be applied without damaging the a-a section?
