Question

The rotor (flywheel) of a toy gyroscope has a mass of 0.120{ m { m kg}} . Its moment of inertia about its axis is 1.30

The rotor (flywheel) of a toy gyroscope has a mass of 0.120{ m { m kg}} . Its moment of inertia about its axis is 1.30 Times 10?4{ m kg cdot m^2} . The mass of the frame is 2.75 Times 10?2{ m { m kg}} . The gyroscope is supported on a single pivot (see the figure below (Figure 1) ) with its center of mass a horizontal distance of 4.15{ m { m cm}} from the pivot. The gyroscope is processing in a horizontal plane at the rate of 1.25 revolution in 2.05{ m { m s}} . Find the upward force exerted by the pivit. Find the angular speed with which the rotor is spinning about its axis, expressed in { m rev/min}.
