The starter motor is driven by
A. Chain drive
B. Gear drive
C. Flat belt drive
D. V-belt drive
Answer: Option B
Solution (By Examveda Team)
The correct answer is (B) Gear driveLet's break down why:
* The starter motor's job is to crank (turn) the engine to get it started.
* It needs to apply a lot of torque (twisting force) to the engine's flywheel.
* Gear drives are perfect for this because they can efficiently transfer power and increase torque.
* Here's why the other options aren't as good:
* Chain drives: While strong, they're usually used for transferring power over longer distances, not inside a compact engine compartment and tend to be noisier.
* Flat belt drives: These are prone to slipping, especially under heavy load. They aren't reliable enough for starting an engine.
* V-belt drives: Similar to flat belts, they can slip, although they are generally better at transmitting power than flat belts but still not as effective as gears for starter motor application.
* In summary: Gear drives are robust, reliable, and ideal for the high torque needed to start a car engine.
The starter motor is driven by electrical power through the vehicle battery itself.
