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 ...

The angular momentum principle says that the net torque (about the center) is equal to the moment of inertia times the angular acceleration of the disk (about the center).

SAE International Journal of Transportation Safety, Vol. 5, No. 2 (July 2017) (14 pages) ABSTRACT SAE J211 provides no definitive specification as to the appropriate procedures for filtering angular ...
