The rotor (flywheel) of a toy gyroscope has mass 0.150 kg. its moment of inertia about its axis is 1.20 × 10−4kg2. the mass of the frame is 2.70 × 10−2kg. the gyroscope is supported on a single pivot (fig. 1) with its center of mass a horizontal 5 distance of 4.00 cm from the pivot. the gyroscope is precessing in a horizontal plane at the rate of one revolution in 2.30 s.
(a) find the upward force exerted by the pivot.
(b) find the angular speed with which the rotor is spinning about its axis, expressed in rev/min.
