What effect does the crankshaft have when converting movement?

The crankshaft plays a critical role in converting the linear motion of the piston into rotary motion, which is essential for the effective operation of an engine. When the pistons move downward due to the combustion of fuel, the crankshaft acts on the connecting rods linked to the pistons. This mechanism transforms the piston's linear movement into rotational motion, which is necessary for the engine to turn the crankshaft and ultimately drive the vehicle.

This rotational force generated is referred to as torque. Torque is a measure of the rotational force that can cause an object to rotate about an axis. In the context of an engine, torque is crucial because it determines how effectively the engine can do work, whether it is moving the vehicle, driving accessories, or powering machinery. The more effectively the crankshaft converts the linear movement of the pistons into torque, the better the engine's performance.

On the other hand, increasing friction could hinder the efficiency of movement, and generating electrical energy is not a primary function of the crankshaft but rather of components like the alternator. Additionally, while it is important for an engine's power output, the direct function of the crankshaft is not to decrease it but to facilitate the conversion process necessary for generating torque. Therefore, the role
