Assignment:
A cantilever beam is to be made using a symmetrical I section beam. The cantilever is to carry a load of 40kN at a distance 2.5m from the fixed end. The situation allows for a depth of I-beam to be no greater than 250mm. I-beams of this depth are normally supplied with a flange of thickness 8mm and web thickness of 6mm. Calculate the flange width if the maximum tensile stress is not to exceed 180MN/m2.
Explain and show calculations.
