2L 0.3L D 0.2L A non-uniform rod AB, of length 24 metres and mass 10 kg, is supported at points and D, with AC -0.3L and DB =0.2L metres. A particle of mass M, kg is suspended vertically at the mid-point of the rod, such that the rod lies in equilibrium in a horizontal position. The reaction forces at C and D are 123 Newtons and 139 Newtons respectively. (a) Find the value of M. (b) Find, in terms of the distance of the centre of mass of the rod from A. In addition to mass M., a second particle of mass M, kg is attached to the rod at B and hangs vertically, and the rod is on the point of tilting about D. (c) Find the value of M.
