C is verticallybelow 0 when the body is in equilib-rium. Let the body be swung to oneside through the angle <p, as shown.Then the force, Mg, with which theearth pulls the body tends to swing thebody back to the vertical position with atorque T which is equal to the productof Mg and the length of… … Fig. 59. T = Mgx-v* (ii) Comparing this with equations (38) and (40), we find that 4t2K = Mgx (41) *Of course this equation may be written T=-Mgx ■ <t> because T tends toreduce 4>. ROTATORY MOTION. 157 in which K is the moment of inertia of the body about the axis0, t is the period of one…
