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 maximize ...

A cable connects block B to point A on the interior of the disk. We want to know the angular acceleration of the disk on release from rest. Watch the animation of the motion of the disk. What do you ...

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 ...
