( NEW VARIABLES ) Now, consider that the inclined structural member is subjected to a compressive force of F = [F] lb applied at an angle of θ = [theta]° with respect to the horizontal. The geometry of the system is defined by the following lengths:- AB = [AB] in- BC = [BC] in- AD = [AD] in- DE = [DE] in The thickness of all members is constant and given as b = [b] in. Using this information, calculate the internal normal and shear stresses at the specified cross sections. Calculate:(1) Average shear stress on AB
