Rotational Equilibrium

A uniform diving board , of length 5.0 m and mass 55 kg , is supported at two points ; one support is located 3.4 m from the end of the board and the second is at 4.6 m from the end . What are the forces acting on the board due to the two supports when a diver of mass 63 kg stands at the end of the board over the water ? Assume that these forces are vertical . [Hint : In this problem , consider using two different torque equations about different rotation axes . This may help you determine the directions of the two forces ] .
