Which statement about connecting rods and camshaft is correct?

Which statement about connecting rods and camshaft is correct?

• A. Technician A Only
• B. Technician B Only
• C. Both A and B
• D. Neither A nor B

Answer: (A)

The main idea is how motion is transferred and timed inside an engine. The connecting rod links the piston to the crankshaft, converting the piston’s back-and-forth movement into the crankshaft’s rotation. The camshaft, on the other hand, controls the valves—opening and closing them at precise times to allow air and fuel in and exhaust out. This timing is coordinated by the engine’s timing mechanism so that valve events line up with the piston positions during the four-stroke cycle (typically with the camshaft turning at half the crankshaft’s speed). A statement that correctly captures these roles is the best choice: it accurately describes the connecting rod as transmitting motion between piston and crankshaft and the camshaft as governing valve timing. Statements that claim the camshaft drives the piston or that the connecting rod operates valves would be incorrect. If you share the exact wording of what Technician A and Technician B said, I can point out exactly why Technician A’s statement matches how these parts function.
