Final answer:
The pinion gear is at the end of the starter motor and meshes with the flywheel to start the engine. The flywheel provides inertia that smooths out engine vibrations and maintains
Step-by-step explanation:
The correct answer is that the pinion gear, which meshes with the engine flywheel gear teeth to start the engine, is located at one end of the starter motor. This pinion gear engages with the teeth on the flywheel when the ignition switch is turned, causing the engine to start.
The flywheel is critical not only for starting the engine but also for smoothing out engine vibrations. It accomplishes this through its heavy weight, which provides a stabilizing inertia to counteract the uneven torque generated during the firing of individual pistons.
By maintaining a more constant angular velocity, the flywheel helps to keep the engine running smoothly.
The correct answer is option the end with the pinion gear. The pinion gear is located on the end of the starter motor, which is the part responsible for starting the engine.
It meshes with the flywheel gear teeth, which are located on the engine's flywheel. When the starter motor is activated, the pinion gear engages with the flywheel gear teeth, allowing the starter motor to rotate the flywheel. This rotation provides the necessary momentum to start the engine.
