The video tutorial explains the function and mechanics of differentials in cars, focusing on rear-wheel drive systems. It covers the need for differentials to allow wheels to rotate at different speeds, especially when turning. The tutorial details the components and operation of open differentials and introduces limited slip differentials, which provide better traction on slippery surfaces. The video also highlights the importance of gear ratios in balancing fuel efficiency and acceleration.

Why is it important for the rear wheels to rotate at different speeds during a turn?

What happens when a car with an open differential travels over a slippery surface?

What role do the spider gears play in the operation of a differential?

How does the friction between the clutch packs in a limited slip differential help in maintaining traction?
