Yes, it would seem at first thought that the ω would not have any effect upon the force required to change the position of the axle. However, when you look at simple gyroscopes this thought is shown to be incorrect. For instance, bicycle wheels use this concept to remain upright while in...

Ok, say you have a wheel, of a given radius 'r' and a given mass 'M', spinning on an axle at a high RPM rate 'ω', and the axle is extended by a given distance 'd' on one end. The wheel is fixed in a way to prevent nutation and precession, so that it can only rotate along its spin axis 'x' and...

Thanks for the replies and links!

So I'm doing some research regarding firearms and need to know the amount of force on the bolt assembly as the bullet is fired. Using a .45 caliber Federal bullet, the mass of the projectile is 15 g, the energy is 500j, and the Vf is 260 m/s. I need to know how to convert these numbers into a...
