A bridge, as shown below, shall carry a distributed load of 280 kN/m2. For the given load and assuming Fy = 345 MPa: 1) Find the smallest W section that carries the applied shear load. 2) Find the smallest W section that carries the applied moment. 3) Design the beam by considering the shear, moment, as well as a deflection limit of L/240. The hot-rolled, i.e., prefabricated, W sections have limited sizes. Assume that the load has been increased dramatically, and we cannot use prefabricated W sections

Question
A bridge, as shown below, shall carry a distributed load of 280 kN/m2. For the given load and
assuming Fy = 345 MPa:
1) Find the smallest W section that carries the applied shear load.
2) Find the smallest W section that carries the applied moment.
3) Design the beam by considering the shear, moment, as well as a deflection limit of L/240.
The hot-rolled, i.e., prefabricated, W sections have limited sizes. Assume that the load has been
increased dramatically, and we cannot use prefabricated W sections. In this case, what would be
your suggestion to have a beam that is able to carry the load? (Provide at least three suggestions.)
