Question

The structural component used for a bridge is shown in the attached image. The length of the beam is 4 m and is simply supported at each end. Neglecting the mass of the beam, calculate the reactions R_Aand R_B at the supports when the beam is in equilibrium.
Also, consider the addition of a uniformly distributed load 7 kN/m for the entire length of the beam; recalculate the support reactions at the end and comment on your findings.
