Question

which of these components convert reciprocating movement of the pistons into rotary motion?
select one:
o a. camshaft
o b. crankshaft
o c. flywheel
o d. piston rings

Explanation:

The crankshaft is a key component in an engine. Its design and function are specifically related to converting the linear (reciprocating) motion of the pistons, which move up and down in the cylinders, into rotational (rotary) motion. This rotary motion is then used to power the vehicle or machinery.

• A camshaft controls the opening and closing of engine valves, not related to converting piston motion to rotary.
• A flywheel stores rotational energy and smooths out engine operation but does not convert the piston's reciprocating motion.
• Piston rings seal the piston - cylinder interface and control oil consumption, not involved in motion conversion.

Answer:

B. Crankshaft
