Introduction You might have seen figure skaters spinning around quickly and then tucking their arms to spin faster—or opening them to spin more slowly. This happens, thanks to a physics concept known ...

Consider the rotor of a gyroscope. The rotor is attached to a frame that is rotating about a fixed vertical axes with a constant rate of ω 1, and with the rotor rotating relative to that frame at a ...

If the angular velocity of a link in a mechanism is zero, does this imply that the angular acceleration of that link is also zero? The short answer to that question is NO. If ω(t) represents the ...
