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 & M,= 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 Marks) (b) The second moments and product second moments of area (10 Marks) (c) The maximum direct stresses at point 1, 2 and 3. (10 Marks) (5 Direct stresses due to bending moments in a beam are given by: 24 mm 1.25 mm 11.25 mm 2 36 mm Figure Question 4
