Answer :
The statement that a driving hub and non-driving hub are identical is false; driving hubs are involved in power transmission, whereas non-driving hubs simply support the wheel. The comparison to a top's simultaneous rest and motion in parts is not applicable to hubs.
The statement that a driving hub and non-driving hub are identical is false. A driving hub typically includes components for power transmission to the wheel such as an integrated motor in the case of some electric vehicles, eliminating the need for a transmission. This is part of what simplifies vehicle dynamics models. On the other hand, non-driving hubs do not facilitate power transmission but may serve to support the wheel and enable free rotation. The dynamics of the wheel of a vehicle, whether it's part of a driving hub or a non-driving hub, involves the entire wheel having the same angular position, velocity, and acceleration at any given time. Additionally, in both static and dynamic situations, idealized models assume external forces and torques to be zero, while considering high speed and other moving mechanical devices. It is also noteworthy that an object, like a spinning top, can have parts that are simultaneously at rest and in motion, but this doesn't apply to hubs because the stationary and moving parts do not exhibit contrary actions at the same point.
