What component on an engine changes the reciprocating motion of the pistons into rotary motion?*1 pointd) Flywheela) Connecting rodc) Camshaftb) Crankshaft

Break Down the Problem

1. Identify the components of an engine.
2. Determine which component is responsible for changing reciprocating motion into rotary motion.

Relevant Concepts

• Reciprocating Motion: Motion in a back-and-forth linear direction, primarily seen in pistons in an engine.
• Rotary Motion: Circular motion around an axis.

Analysis and Detail

• The pistons in an engine move up and down (reciprocating motion).
• This motion needs to be converted into circular (rotary) motion to turn the crankshaft and ultimately drive the vehicle's wheels.
• The crankshaft is the component specifically designed to perform this conversion.

Verify and Summarize

• Options Analysis:
  • a) Connecting rod: Transmits motion from the piston to the crankshaft.
  • b) Crankshaft: Converts the reciprocating motion of the pistons into rotary motion.
  • c) Camshaft: Controls the opening and closing of engine valves.
  • d) Flywheel: Stabilizes the rotational speed but does not convert motion.

Final Answer

The component that changes the reciprocating motion of the pistons into rotary motion is b) Crankshaft.
