A steel cantilever beam, of length L=1 m, has a hollow rectangular cross-section, see Figure Q3. The outside width and height of the rectangular cross-section are b=148 mm and h=273 mm, respectively, and the wall thickness is 8 mm. A point force of P=200 kN is applied at the free end of the cantilever beam. The yield strength of the steel is [o] = 304 MPa. The coordinates of Point H are x=-75 mm, y=0 mm, z= -70 mm.
