Angular acceleration in 3D 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 ω1, and with the rotor rotating ...
With a plot of angular position as a function of time, we can use the angular kinematic equation for an object with a constant angular acceleration.
At t 2, the angular velocity is zero, with a non-zero (positive) angular acceleration. At that time, the direction of rotation for BC is changing from CW to CCW. In summary, you should never assume ...
