INTRODUCTION
Some bodies like pulley, shafts, flywheels etc., have motion of rotation (i.e., angular motion) which takes place about the geometric axis of the body. The angular velocity of a body is always expressed in terms of revolutions described in one minute, e.g., if at an instant the angular velocity of rotating body in N r.p.m. (i.e. revolutions per min) the corresponding angular
velocity รน (in rad) may be found out as discussed below :
