Why differential gears are used

The video tutorial explains the role and function of differentials in cars. It covers the location of differentials in rear-wheel, front-wheel, and four-wheel drive vehicles. The tutorial details how differentials distribute power to wheels, allowing them to rotate at different speeds, especially when turning. It highlights the importance of differentials in preventing tire wear and axle damage. The video also contrasts open differentials with limited slip differentials, explaining how the latter helps in maintaining traction on slippery surfaces.

Describe the difference between an open differential and a limited slip differential.

What issue arises when a wheel travels over a slippery surface with an open differential?
