Question:

How can we interpret wheel-balancing by means of physical principles?

How can we interpret wheel-balancing by means of physical principles Such as TORQUE and FORCE and VECTORS?

Answer:

nothing works well on ice. Front wheel drive starting on a slight hilll will leave you spinning. I have seen it many times,s I drive by.LOL I use 4WD. It is not the same as quattro and AWD. Those have viscous transfer cases that divide the torque up to any wheel in any percentage of torque to that wheel. 4wd can be locked so that torque goes to all the wheels all the time. You can't drive 4wd on dry roads, but you can drive AWD on dry roads.
4 wheel drive is the same as all wheel drive is the same as quattro. Rear wheel drive is useless in snow or ice. Front wheel drive is better than rear wheel drive, but if the car has wide low profile tyres, as is now the norm, then things get hairy ! Four wheel drive is the best and that is why it fitted on cars such as the Audi.The first Audi quattro were built for the Austrian/Swiss and German alpine markets. One thing to consider with any drive system, if the tyres lose their grip, you are going to have to avoid the first stationary object you come across !!!!
none of them are good on icy roads-you just have to drive slow. In deep snow probably 4-wheel drive, for curvy roads all wheel drive but front wheel drive is good in snow if you do not race. I own vehicles with 4-wheel drive, all-wheel drive, front and rear wheel drive. Even my rear wheel drive volvo went well in the snow.
Automobile wheel balancing is basically moving the center of mass closer to the center of rotation of the wheel. When the wheel is at rest, it should not rotate because there is no torque acting on the wheel. If the wheel were unbalanced, there is a torque which is equal to the amount of eccentricity (distance the center of mass is away from the center of rotation) multiplied by the weight of the wheel
