9 Figure 3 A uniform rod AB, of mass m and length 2a, is freely hinged to a fixed point A. A particle of mass m is attached to the rod at B. The rod is held in equilibrium at an angle to the horizontal by a force of magnitude Facting at the point C' on the rod, where AC = b, as shown in Figure 3. The force at C acts at right angles to AB and in the vertical plane containing AB. It can be shown that F - B 3amg cos b Find, in terms of a, b, g, m and 0, the horizontal component of the force acting on the rod at A.
