The beam weight is 200 kN considered as a distributed load over the
beam length. In addition, in the worst case, loaded trucks with an
average mass of 20 tons each will pass the bridge, they can pass
the bridge together or individually. You only need to take the
self-weight and truck loads into account in your calculations.
Hint: you can consider two loads on the beam for each truck or one
load including the weight of both trucks.
A) Draw the shear force diagram and bending moment diagram based
on the loading condition and derive the equations for bending
moment and shear force.
B) Determine the size of I beam with specifications shown below
with the smallest possible section that can carry the bending
moment in the simply supported beam. Maximum allowable stress is 60
kPa.
