If a car is making a left turn which wheel turns faster?

Question:

What is wrong with our car?

Its the outside wheel. In the case of a left turn it would be the wheel on the right by the passenger's side. If you were looking at the car turning from a top view and you put white paint on the tires, you would be able to see that both tires would make a 1/4 circle and that the inside tire made a smaller 1/4 circle which would have made a complete circle with a smaller radius than the outside tire. if the outside wheel of your car travels on a circular path, the wheel would travel faster than the inside wheel because it has to travel a longer path than the inside circle because the circumfrence is always more on the bigger circle. Just imagine putting a peice of string a long both the white tire marks that you car would have made. then extend both peices of string straight. You would find that the string for the outside wheel is longer than the one for the inside wheel. That proves that the outside wheel has to travel a longer distance in the same amount of time. Its a visual explenation of why the outside tire would travel faster. I think its easier to explain that way. Hope this helps. Just visualize. If not, ask your math teacher.

Is there a website to get average prices for auto repairs?


That is why it is dangerous to drive your 4x4 truck on the road while making turns. The 4x4 system locks both tires together if it doesn't have a limited slip differential. When turning one of the tires would try to spin faster but the inside tire would not let it because they are locked together, causing the vehicle to flip. That is why on cheaper cars only on of the back tires spin. They are not locked and when you turn it wouldn't flip the vehicle over because all the tires are independent of each other. On vehicles that cost more money they are equipped with a limited slip differential that lets both tires spin while going straight AND lets them travel at their own independent speed when the vehicle is turning. Look up a limited slip differential on www.howstuffworks.com for a better understanding.
