What is the main function of a clutch?
To transmit the engine power to the rear wheels without shock
To exchange engine power for greater torque
To provide reverse motion
To regulate torque
What is the purpose of a differential in a vehicle?
To regulate torque by selecting the appropriate speed range
To provide reverse motion
To balance the tractive effort with the sum of the various forces tending to oppose the motion
To exchange engine power for greater torque
What is the advantage of a fluid flywheel over a torque converter?
Torque multiplication unit 3:1 to 4:1
Requires less maintenance and attention
Serves as an automatic clutch
No wear of moving parts
What is the main function of a gear box?
To provide neutral position and disallow power flow to the rest of the transmission
To transmit the engine power to the rear wheels without shock
To exchange engine power for greater torque
To regulate the vehicle speed at which maximum torque is available
What is the construction of a semi-floating axle?
The bearing is located between the axle casing and the hub
The weight being completely supported by the wheels and the axle casing
The axle shaft carry only the driving torque
The outer end is supported by a single bearing inside the axle casing
What is the main purpose of a propeller shaft?
To transmit the drive from the transmission to the bevel pinion or worm of final drive in front engine, rear drive vehicle
To exchange engine power for greater torque
To provide reverse motion
To transmit the engine power to the rear wheels without shock
What is the requirement of a clutch related to heat dissipation?
The clutch should have suitable mechanism to damp vibrations and to eliminate noise produced during the power transmission
The clutch should engage gradually to avoid sudden jerks
The clutch should be dynamically balanced
The clutch should be able to dissipate large amount of heat which is generated during the clutch operation due to friction
What is the advantage of a single plate clutch?
The construction is very simple
The plate is mounted on a hub which is splined from inside and thus free to slide on gear box shaft
The driven member of the clutch should be made as light as possible
The friction lining can be replaced as and when required
What is the working principle of a centrifugal clutch?
The oil from the driving member is forced outward radially because of the centrifugal force
The centrifugal force is used to apply pressure on clutch to keep in engaged position
The pressure plate is moved to the right against the force of spring, releasing the friction plate
The throw out bearing moves towards the flywheel, pressing the centre portion of the spring
What is the main function of a transmission system?
To provide for the relative movement between the engine and the driving wheels due to flexing of the road springs
To turn the drive round through 90 degrees
To enable the driving wheels to be driven at different speeds
To enable the engine to be disconnected from the road wheels
What is the function of a universal joint in a propeller shaft?
To transmit power at an angle between the driving and driven shafts
To provide reverse motion
To exchange engine power for greater torque
To regulate torque
What is the purpose of a synchromesh gearbox in a vehicle?
To provide smooth and easy shifting of gears without grinding
To exchange engine power for greater torque
To regulate the vehicle speed at which maximum torque is available
To transmit the engine power to the rear wheels without shock
What is the advantage of a double clutch transmission system?
Allows for quicker gear changes compared to traditional manual transmissions
Provides reverse motion
Reduces the need for clutch replacement
Enables the engine to be disconnected from the road wheels
What is the function of a torque converter in a vehicle?
To provide reverse motion
To exchange engine power for greater torque
To regulate the vehicle speed at which maximum torque is available
To transmit power through hydraulic fluid coupling
What is the purpose of a flywheel in an engine?
To provide reverse motion
To store rotational energy and smooth out engine power pulses
To exchange engine power for greater torque
To regulate torque
What is the main function of a differential in a vehicle?
To regulate torque by selecting the appropriate speed range
To provide reverse motion
To balance the tractive effort with the sum of the various forces tending to oppose the motion
To exchange engine power for greater torque
What is the main function of a drive shaft in a vehicle?
To transmit power from the transmission to the wheels
To provide reverse motion
To exchange engine power for greater torque
To regulate torque
What is the purpose of a synchronizer in a manual transmission?
To provide smooth gear engagement by matching the speed of gears
To exchange engine power for greater torque
To regulate the vehicle speed at which maximum torque is available
To transmit the engine power to the rear wheels without shock
What is the advantage of a limited-slip differential over an open differential?
Provides better traction by limiting wheel slip
Allows for reverse motion
Reduces the need for clutch replacement
Enables the engine to be disconnected from the road wheels
What is the function of a torque converter in a vehicle?
To provide reverse motion
To exchange engine power for greater torque
To regulate the vehicle speed at which maximum torque is available
To transmit power through hydraulic fluid coupling
