... b) A flywheel with a moment of inertia I = 5 kg m2 is mounted on a light axle. It is initially stationary. A torque of 100 N m is applied to the axle for 100 s. (i) Calculate the final angular velocity of the flywheel. v = u + at = u + F/m t, so f = I + t = 0 + /I t = 2000 rads–1. (ii) Calculate ...

Precession
Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, the axis of rotation of a precessing body itself rotates around another axis. A motion in which the second Euler angle changes is called nutation. In physics, there are two types of precession: torque-free and torque-induced.In astronomy, ""precession"" refers to any of several slow changes in an astronomical body's rotational or orbital parameters, and especially to Earth's precession of the equinoxes. (See section Astronomy below.)
