0 5a B 3a 20 A A uniform rod AB of length 3a and weight W is freely hinged to a fixed point at the end A. The end B is below the level of A and is attached to one end of a light elastic string of natural length 4a. The other end of the string is attached to a point O on a vertical wall. The horizontal distance between A and the wall is 5a. The string and the rod make angles 0 and 20 respectively with the horizontal (see diagram). The system is in equilibrium with the rod and the string in the same vertical plane. It is given that sin 0 = 2 and you may use the fact that cos 20 7 - Find the angle that the force acting on the rod at A makes with the horizontal. 0 5a B 3a 20 A A uniform rod AB of length 3a and weight W is freely hinged to a fixed point at the end A.
