Question
The angular momentum vector of a precessing gyroscope sweeps out a cone as shown in the figure below. The angular speed of the tip of the angular momentum vector, called its
precessional frequency, is given by t/L, where ris the magnitude of the torque on the gyroscope and L is the magnitude of its angular momentum. In the motion called precession
of the equinoxes, the Earth's axis of rotation precesses about the perpendicular to its orbital plane with a period of 2.58 x 10 yr. Model the Earth as a uniform sphere and calculate the
torque on the Earth that is causing this precession.
