A steel cantilever beam of length L = 1m has a hollow rectangular cross section. The outside width and height of the cross section are b = 100mm and h = 271mm respectively and the wall thickness is 8mm. A point force of 212kN is applied at the free end of the cantilever beam. The yield strength of the steel is 290MPa. The coordinates of Point H are x = -75mm, y = 0mm, z = -46mm. Please help me calculate the factors of safety predicted at point H by the maximum shear stress theory of failure. (Tresca criterion)
