MEV321: Chapter 3 (Transmission System)

What is the primary function of a manual transmission?

• To automatically shift gears

• To provide a direct drive

• To increase fuel efficiency

• To allow the driver to select gears manually

Which component is used in a manual transmission to prevent gear clash during shifting?

• Gear lever

• Torque converter

• Synchronizer

• Clutch

What does the gear ratio in a manual transmission indicate?

• The type of lubricant used

• The amount of torque produced

• The relationship between the input and output speeds

• The number of gears in the transmission

In a manual transmission, what is the typical gear ratio for first gear?

• 0.8:1

• 4:1

• 2.4:1

• 1:1

What is the purpose of a torque converter in an automatic transmission?

• To provide manual gear selection

• To convert engine power to hydraulic pressure

• To increase engine speed

• To reduce fuel consumption

Which type of gear set is commonly used in automatic transmissions?

• Planetary gear set

• Spur gear set

• Bevel gear set

• Worm gear set

What is the main advantage of a continuously variable transmission (CVT)?

• Fixed gear ratios

• Smooth acceleration without shifting

• Higher top speed

• Lower manufacturing cost

What is the function of a differential in a vehicle?

• To reduce fuel consumption

• To allow wheels to rotate at different speeds during turns

• To provide a direct drive

• To increase engine power

Which type of differential allows for limited slip between the wheels?

• Open differential

• Standard differential

• Viscous limited slip differential

• Locked differential

What is the purpose of a universal joint (UJ) in a drivetrain?

• To connect the engine to the transmission

• To allow for angular movement between shafts

• To increase torque output

• To reduce friction in the drivetrain
