3. Read and translate the text. Clutch

The transmission system of a car is a series of assemblies which purpose is to transmit the power of the engine to the road wheels. The first of theses is the clutch assembly. This enables the remainder of the transmission system to be disconnected from the engine, when necessary, so that the various gears in the gearbox can be engaged.

At the back of the engine is a heavy flat wheel known as a flywheel. It is attached to the rear end of the crankshaft and revolves with it. A clutch plate consisting of a metal disc with a friction lining round its outer edge, is held firmly against the flywheel by a spring-loaded pressure plate. As the flywheel revolves the clutch plate revolves and it is simply the pressure of one against the other that provides the drive from engine to transmission.

The clutch is operated by the clutch pedal inside the car. When the driver depresses the pedal the clutch pressure plate is forced away from the flywheel, thus disconnecting the engine from the transmission. When the pedal is released, the pressure plate forces the clutch plate against the flywheel and the drive is taken up again.

4. Answer the questions:

1) What system of a car transmits the power of the engine to the road wheels?

2) What device is used to engage or disengage the flow of power from an engine to a transmission?

3) Where is a flywheel placed?

4) What does a clutch plate consist of?

5) What does the pressure of the clutch plate against the flywheel provide?

6) What is the purpose of the clutch pedal?

5. Say with one word:

1) gear unit that varies the relative speed of the engine and the driving wheels to produce the proper amount of torque for different driving situations

2) coupling device used to engage or disengage the flow of power from one moving part to another, such as from the engine to the transmission

3) heavy metal disc attached to the crankshaft that smoothes out variations in torque and thus keeps the shaft turning at a near constant speed

4) turning or twisting force

6.Find the right translation:

1.Встановлювати - to revolve, to place, to vary

2.Забезпечувати - to provide, to drive, to take up

3.Закріпляти - to keep, to attach, to consist

4.Виробляти - to place, to engage, to produce
