A 3 kg bicycle wheel rotating at a 2941 rev/min angular velocity has its shaft s

Question

A 3 kg bicycle wheel rotating at a 2941 rev/min angular velocity has its shaft supported on one side, as shown. When viewing from from the left (from the positive x-axes), one sees that the wheel is rotating in a Counter-clockwise manner. The distance from the center of the wheel to the pivot point is 0.5 m. The wheel is a hoop of radius 0.5 m, and its shaft is horizontal.

a) Find the change in the precession angle after a 1.3 s time interval. Assume all of the mass o the system is located at the rim of the bicycle wheel. The acceleration to gravity is 9.8 m/s^2. Answer in units of degrees.

b)What is direction of precession viewed from the top?

Explanation / Answer

Assume all the mass of the system is located at the rim of the bicycle wheel. The acceleration of gravity is 9.8 m/s^2.

Find the change in the precession angle after a 1.5 s time interval.

In my book I have the equation:
