The rotor (flywheel) of a toy gyroscope has mass 0.150 kg. Its moment of inertia about its axis is 1.20x10^-4kgm^2. The mass of the frame is 2.60×10?2 kg. The gyroscope is supported on a single pivot (Figure 1) with its center of mass a horizontal distance of 4.00 cm from the pivot. The gyroscope is precessing in a horizontal plane at the rate of one revolution in 2.10s .
A: Find the upward force exerted by the pivot.
F=________ N
B: Find the angular speed with which the rotor is spinning about its axis, expressed in rev/min.
w=rev/min.
