Table Top Physics - Angular Momentum - Gyroscope

The small blue flywheel is rotating at a constant angular velocity of w₁, the base wheel is rotating at a constant angular velocity of w₂.

gyroscope

What is the angular momentum of the complete system?

Is the angular momentum of the complete system a funtion of time? In other words, does it require external torque to keep it going?

Would the angular momentum be constant if w₁= w₂?

Further Information

These pages contain examples to illustrate the principles involved, for an discussion of the theory about angular momentum see this page.

Dark Basic Professional Edition - It is better to get this professional edition

This is a version of basic designed for building games, for example to rotate a cube you might do the following:
make object cube 1,100
for x=1 to 360
rotate object 1,x,x,0
next x

Can you help?

Please send me any improvements to here. I would appreciate ideas to make the pages more useful including error correction, ideas for new pages, improvements to wording. It helps if you quote the full URL of the page.
