4. A horizontal beam 4.8m long of mass 18kg is supported by pillars 0.2m from each end. There is man
of mass 85kg standing 1.7m from one end of the beam. Overleaf draw a diagram showing the forces
acting on the beam in this equilibrium condition. Calculate the magnitudes of the loads carried by
each support.
