Required information Consider the loading shown. The allowable normal stress for the steel used is 160 MPa. 0.8 m 50 kN/m B -2.4 m- 0.8 m For the selected design, determine the actual value of Om in the beam. (Round the final answer to one decimal place. You must provide an answer before moving to the next part.) The actual value of om in the beam is 160 MPa.

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? %3D %3D (Please solve in detail and according to engineering rules.)
