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 ...

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".

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 ...
