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 ...

Cross-flow turbines, also known as vertical-axis turbines, are attractive for power generation from wind and water currents. Some cross-flow turbine designs optimize unsteady fluid forces and ...

The angular acceleration tells you how the angular velocity changes with time. It's just like plain acceleration is to plain velocity. I like to call the moment of inertia the "rotational mass".
