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 in the a-a section shown in the figure,

b) show (draw) the distribution of normal stresses along the section height,

c) Clamp material tensile safe tension σ_safety
Since = 50 MPa and compression safety stress σ_safety
= 80MPa, what is the maximum compressive load (P) that can be applied without damaging the a-a section?
