A spherical mass, m$,$ sits on a horizontal $($massless$)$ beam that is attached to two supports $($red on the left, blue on the right$).$ Rank the magnitude of the $3$ forces on the horizontal beam, where Fs is the force the spherical mass exerts on the beam, FL is the force exerted by the left $($red$)$ support

and FR is the force exerted by the right $($blue$)$ support.
