a shaft that converts the up and down motion of the pistons into rotational motion
A crankshaft is a long, heavy rod in a vehicle's engine that converts the up-and-down motion of the pistons into rotary motion, which turns the wheels. It is connected to the pistons through rods, and as the pistons move, they cause the crankshaft to rotate. This rotation helps drive the vehicle forward. The crankshaft is made of strong metal to withstand the force of the engine and is an essential part of the engine's power system. It is also linked to other parts of the vehicle to ensure smooth engine operation.
