A uniform T-section is 120 mm wide and 180 mm deep with a flange thickness of 25 mm and a web thickness of 12 mm as shown in Figure 3. If the limiting bending stresses for the material of the beam are 80 MPa in compression and 160 MPa in tension, find the maximum uniformly distributed load, w what the beam can carryover a simply supported span of 6 m.
