The screwed 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 pressure load (P) that can be applied without damaging the a-a section?

Extracted text: 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 the section a-a shown in the figure. b) Show the distribution of normal stresses across the section height. (draw) c) Since the clamp material has tensile strength (apull) safety = 50MPA and compression safe stress (opress) safety = 80MPA, what is the great compressive load (P) that can be applied without damaging the a-a section?
