Question #4(25 Marks) Figure Q4 shows a thin-walled cantilever beam that supports shear loads at its free end. Maximum bending moments caused by applied shear loads are Mx= - 5000 N.mm & My= 8000 N.mm Assume that the position of shear loads is such that no twisting of the beam occurs. Calculate (a) The centroid of the cross section (b) The second moments and product second moments of area (c) The maximum direct stresses at point 1, 2 and 3.
