Final answer:
The correct answer is A) Damper pulley. A damper pulley is a heavy wheel that is mounted on a rubber ring and keyed to the crankshaft snout. It acts as a counterweight to reduce vibrations in the crankshaft and minimize damage to the engine vibrations and ensures smooth operation.
Step-by-step explanation:
The correct answer is A) Damper pulley. A damper pulley is a heavy wheel that is mounted on a rubber ring and keyed to the crankshaft snout. It acts as a counterweight to reduce vibrations in the crankshaft and minimize damage to the engine. The rubber ring helps absorb the shock and noise generated by the engine. For example, in a car engine, the damper pulley is located at the front of the engine and is connected to the crankshaft. It helps reduce engine vibrations and ensures smooth operation.
