Electrical system → to supply and control electrical power • battery stores energy in 1. form → electricity to run electrical components •2. → mechanical energy into 3. energy → recharges battery using mechanical energy generated by 4. of parts
Braking system → to stop or slow vehicle For example, 5. system, whose parts are: • caliper → contains 6. components → brake pads against 7. • brake rotor → disc-shaped, revolves with 8. and wheel → provides 9. surface •10. → applies pressure and friction to brake rotors
Transmission system → transfers power from engine to 11. Types: • automatic → gear ratios automatically 12. by engine computer •13. → stick for shifting gears and pedal for 14.
17.1 Say if the sentences are true (Vero) or false (Falso).
1. A car’s main systems include the transmission, braking, and electrical systems.
2. A battery stores mechanical energy to run the vehicle’s electrical components.
3. The alternator converts mechanical energy into electrical energy.
4. The braking system is used to slow down or stop the vehicle.
5. The caliper contains hydraulic components that force the brake pads against the rotor.
6. The brake pad is the disc-shaped component that revolves with the hub and wheel.
7. The transmission system transfers power from the engine to the wheels.
8. In manual transmission, gear ratios are controlled by a computer.
