A. Fill in the blanks:
1. _______________ and _______________ are the components of transmission system.
Ans: Gearbox, clutch.
2. Propeller shaft helps ________________ in an engine.
Ans: Transmit the power.
3. Function of differential unit is to ____________.
Ans: Rotate at different speeds.
B. Multiple choice questions:
1. Which system transmits power from the engine to the wheel?
(a) Transmission system.
(b) Fuel supply system.
(c) Power supply system.
(d) Ignition system.
Ans: (a) Transmission system.
2. What assists the gradual engagement and disengagement in transmission of power?
(a) Clutch.
(b) Gearbox.
(c) Crankshaft.
(d) None of the above.
Ans: (a) Clutch.
3. Gear box is placed between __________________.
(a) Clutch and propeller shaft or differential.
(b) Rear axle and engine.
(c) Connecting rod and crank shaft.
(d) None of the above.
Ans: (a) Clutch and propeller shaft or differential.
C. Answer the following questions:
1. What is the importance of a transmission system?
Ans: The transmission system of a vehicle is responsible for transmitting the power from the engine to the wheels. It is also known as the powertrain. This system includes components such as the clutch, gearbox, propeller shaft, and differential unit, which work together to ensure the smooth operation of the vehicle. Regular checks on the transmission system, like fluid levels and filters, help it work smoothly and prevent problems.
2. Give the difference between clutch and gear.
Ans: The differences between clutch and gear are as follows:
| Clutch | Gear |
| The clutch is responsible for engaging or disengaging the engine power from the transmission system. It allows smooth transitions between gears. | Gears are used to control the speed and torque transmitted from the engine to the wheels. They provide different gear ratios for various driving conditions. |
| Enables smooth gear shifting. | Controls vehicle speed and power. |
| A friction-based device (in manual cars, a disc and pressure plate) that can connect or disconnect rotating shafts. | A system of interlocking toothed wheels (cogs) of various sizes. |
| The clutch is located between the engine and the gearbox. | Gears are located within the gearbox or transmission. |
| Facilitates gear shifting. | Transmits power to wheels. |

A. Fill in the blanks:
1. Clutch is used for ____________ and _____________ power.
Ans: Engaging, disengaging.
2. The clutch free play for four-wheelers is generally ______________.
Ans: 15–20 mm.
3. Clutch unit is fixed between _______________ and _____________.
Ans: Engine output shaft, gearbox input shaft.
B. Multiple choice questions:
1. A clutch must also transmit total engine _____________.
(a) Torque.
(b) Power.
(c) Fuel.
(d) Resistance.
Ans: (a) Torque.
2. In a two-wheeler first check the free play of clutch lever, which should be _____________.
(a) 10–12 mm.
(b) 50–60 mm.
(c) 100–150 mm.
(d) None of the above.
Ans: (a) 10–12 mm.
3. Stretch the outer cable or sleeve by turning the tubular screw (adjustment unit) anti-clockwise to ______________.
(a) Reduce the free play.
(b) Increase the free play.
(c) Neutralise free play.
(d) None of the above.
Ans: (a) Reduce the free play.
4. The clutch free play for four-wheelers is generally _________________ at the
clutch pedal.
(a) 15–20 mm.
(b) 20–30 mm.
(c) 40–50 mm.
(d) None of the above.
Ans: (a) 15–20 mm.
C. Answer the following questions:
1. What is the importance of clutch?
Ans: The clutch transmits power completely from the engine to the gearbox without any slippage. The clutch must engage smoothly and disengage completely. For this purpose, there should not be any pivot friction in control cable connection or in clutch linkage
2. What are the effects of binding in a clutch?
Ans: Binding in the clutch creates unnecessary load on the engine, reduces fuel efficiency and causes the clutch plate to wear early. This happens because the clutch fails to engage or release without difficulty, leading to continuous partial contact between clutch components, causing more friction and mechanical resistance.
