A shaft rotating at 3000 rpm is transmitting a power of 3.14 KW . The magnitude of the driving torque is

Moment of inertia of a wheel is 0.004 kg. m^(2) . If its number of revolutions is increased from 60 rpm to 150 rpm in 3 s, determine the magnitude of the torque acting on it.

A wheel is rotating at 900 r.p.m about its axis. When the power is cut off, it comes to rest in 1 minute. The angular retardatin in radian/ s^(2) is (pi)/x . Find the value of x.

A shaft initially rotating at 1725 rpm is brought to rest uniformly in 20s. The number of revolutions that the shaft will make during this time is
