What is the primary purpose of a manual transmission in an automobile?

• To power the vehicle's electrical systems

• To increase fuel efficiency only

• To control the speed and torque to the drive wheels

• To enhance the vehicle's aesthetics

What is achieved by reducing the transmission speed when climbing a hill?

• Higher torque

• Decreased engine load

• Increased speed

• Lower fuel consumption

What principle do manual transmissions operate on?

• Hydraulic force

• Magnetic induction

• Gear ratios

• Electrical resistance

What is a key disadvantage of sliding mesh transmissions?

• High fuel consumption

• Difficulty in sliding gears to engage

• Excessive noise production

• Low torque output

How does a constant mesh transmission differ from a sliding mesh?

• Gears are always engaged

• Gears are never in contact

• Uses hydraulic fluid to change gears

• Operates only at high speeds

What component helps synchronize the gear speed with the shaft in manual transmissions?

• Gear lever

• Synchronizer ring

• Clutch pedal

• Countershaft

What does the sleeve do in a manual transmission system?

• Increases the gear ratio automatically

• Connects the gear to the shaft

• Separates the gears for safety

• Cools down the transmission fluid

What is the main function of the hub in a gearbox?

• To increase the gear ratio

• To hold the synchronizer sleeve

• To generate additional power

• To lubricate the transmission

What action is performed before moving the sleeve in a gearbox?

• Accelerating the vehicle

• Pressing the clutch pedal

• Turning off the engine

• Checking the oil level

Why is it necessary to press the clutch pedal before shifting gears?

• To discontinue power flow to the gear

• To check the transmission fluid

• To increase the engine's RPM

• To activate the vehicle's brakes
