For the other parts, let's focus on two things: the moment of inertia (I) and the angular acceleration (α). The angular acceleration tells you how the angular velocity changes with time.

The goal of the problem is to calculate the angular acceleration of the rotor. The analysis for this is provided below. This result shows that, although both rotation components for the rotor are ...

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 ...

Sometimes it's useful to write the centripetal acceleration in terms of the angular velocity (ω ... With a Little Help From Physics Rose Yu has drawn on the principles of fluid dynamics to ...
