Welcome to PF, Persia7.
You sort of lost me with that question. The rear wheels are turned by a differential, unless you have a front-wheel-drive vehicle. The front ones just free-wheel, unless the brakes are applied. The opposite is true for a FWD thing.
 when two wheels are rigid to axle ,how axle can turn without slip?

It can't. This is why a differential arrangement is used, so both driven wheels can transmit power at different speeds.

Check out the 'how stuff works' article on the same, or build one out of Lego to understand better.

 in front wheel drive cars ,rear axle havent diffrrential , how it can turn?
 cart havent diffrential but how it can turn in corner?
 Recognitions: Gold Member Science Advisor welcome persia on front wheel drive cars, the rear wheels are simply wheels on bearings abd are free to rotate independatly of the drive wheels. They are just along for the ride..savvy?
 if front axle need diffrential to turn (in corner) then why rear wheels doesnt?
 Recognitions: Gold Member Science Advisor the front wheels must transmit power to the road..since rear wheels are not connected to engine..no differential is required..only independant bearings
 please explain what force and how cause rear axle turns in corners ??
 Recognitions: Gold Member This is like talking to a rock, but I'm going to assume that it's an "English as 2nd language" problem. Okay... get yourself a Hot Wheels or Matchbook toy car and check out how the wheels turn. Now imagine a differential on one end of it. That's what we're talking about. Ignore the fact that they don't have steering mechanisms; it's irrelevant here.
 Front wheel drive vehicles have a differential as part of the transaxle. The rear wheels on a front wheel drive vehicle are not locked the same axle. Each one can free-wheel independent of the other. - Rear wheel drive vehicles have a differential in the center of the rear axle. The front wheels on a rear wheel drive vehicle are obviously not locked to the same axle. If they were, steering would be impossible. - - There, I tried.
