A man of mass m1 stands on the edge of a horizontal uniform disc of mass m2 and radius R which is capable of rotating freely abt a stationary vertical axis passing thr its centre.At a certain moment the man starts moving along the edge of the disc :he shifts over an angle @ relative to the disc and then stops.in this process the velocity of mass varies as v(t).Assuming the dimensions of the man to be neglible ,find>
the force moment(relative to the rotation axis)with which the man acted on the disc in the process of motion.

to find:moment of force:f.r=t soln:f.r=I.@ f.R=[m2R^2/2+m1R^2]a/R f =[m2/2+m1]a
