    automobile

    Hi frnds,
    Consider a four wheeler which is lifted from ground. non of it's wheel touches the ground.
    Now vehicle is started, put on first gear and clutch is released.
    Just consider the situation and tell me about the rotation of wheels.
    No brake is applied.

    The driven wheels have to rotate. If it is the usual rear wheel drive. the front wheels will not rotate. Or is that too simple an explanation?

    If its an all wheel Drive 4*4 , Then what happens? Will there be a minute difference between the pair of rear wheels and front ones ?

    Take Mahindra Thar 4*4 as example and please verify us Sir?

    This gives you all info on 4 wheelers:

    hi sir, what abt the left side wheel rotation and that of right side wheel?
    Is there any difference btw the speed of these two wheels?

    No,there will be no difference between the rpm of left and right wheel as the torque required to overcome the inertia and friction effects will be same for both the wheels.

    As Rishab says above, there is no difference ordinarily. However, when the car takes a turn the wheel on the inside curve has to rotate less than the outer wheel. That is taken care of by the differential. In your example the wheels are off ground so there should be no difference in RPM.

    ya, sure. consider the situation that one wheel is lifted and another wheel is in ground. now what will happen?

    It will depend on the type of differential used in the car.if it is an open differential,then only the wheel in air will rotate and that in ground will remain stationary.else if it is locked differential then both the wheel will rotate with same rpm.
    Generally, limited slip differential is used in cars which is somewhere mid-way of the above two differentials.In that case both wheel will rotate with different non-zero rpm.
