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 animation above shows the acceleration of the two centers of mass O and G for the disk and bar, respectively. As expected, the acceleration of O is always along a horizontal line. The direction of ...

In the ideal scenario of a bicycle wheel on a frictionless axle, there is no external torque acting on the wheel once it is set in motion. This is why it continues to spin at a constant angular ...
