# Rotational motion: Rate of precession of a rotating wheel.

A wheel with mass less spokes has mass 1 kg and radius 10 cm and is mounted on one end of a mass less axle as figure.

The axle rests on a pivot at a point 16 cm from the mounting point and 10 cm from the wheel.

At the other end, a mass of 0.8 kg is attached.

The wheel spins at an angular frequency of 10 rad/s.

What is the rate of precession?

Hope you can explain the steps.

Thank you.

Please see the attached file.

A wheel with massless spokes has mass 1 kg and radius 10 cm and is mounted on one end of a massless axle as figure.

The axle rests on a pivot at a point 16 cm from the mounting point and 10 cm from the wheel.

At the other end, a mass of 0.8 kg is attached.

The wheel spins at an angular frequency of 10 rad/s.

what is the rate of precession?

Mass of the wheel M = 1 kg

Radius of the wheel R = 10 cm = 0.1 m

Mass of the body m = 0.8 kg

Angular velocity of the wheel =10 rad/s

Moment of inertia of the wheel about ...

#### Solution Summary

Very good solution to learn concepts of rotational motion. Explaining the precession of a rotating wheel and counter mass on axle. The frequency of precession is calculated.
