Differential

Why do rear wheels need to turn at different speeds when a car turns?

• To reduce wear on the tires

• Because the inner path is longer than the outer path

• To increase the car's speed

• Because the outer wheels must cover a longer distance in the same amount of time

What is the primary function of a differential gear train in vehicles?

• To reduce the vehicle's speed

• To allow wheels to rotate at different speeds

• To increase fuel efficiency

• To power the vehicle's electrical systems

What problem does an open differential solve?

• Prevents the car from accelerating

• Locks the wheels together for better traction

• Increases the car's fuel efficiency

• Allows wheels to rotate at different speeds, preventing tire slip

What issue arises with an open differential when one wheel is on a slippery surface?

• Almost all engine power goes to the wheel with least resistance

• Both wheels stop moving

• The car accelerates faster

• The differential locks up

What is the advantage of building a model differential?

• It can replace the differential in a real car

• It increases the vehicle's performance

• It is a requirement for mechanical engineering students

• It helps in understanding the differential's operation visually

How does a limited slip differential differ from an open differential?

• It reduces the car's fuel efficiency

• It allows the car to move faster

• It locks the rear wheels together permanently

• It prevents power from being transferred to the wheel with less resistance

What components are added in a limited slip differential that are not present in an open differential?

• A second ring gear

• Hydraulic actuators

• Additional spider gears

• Clutch packs and springs

What happens in a limited slip differential when a car turns?

• The clutch packs allow the side gears to rotate at different speeds

• The side gears rotate at the same speed

• The differential stops distributing power

• The clutch packs lock the wheels together
