🔍 Key Concepts

• Locate the stroke length in inches on the MO-0004 data sheet and remember that one revolution moves the piston from TDC to BDC and back. • Recall the standard formula for average piston speed in a reciprocating engine and how RPM and stroke length are used in it. • Be careful with unit conversions from inches to feet and from revolutions per minute to feet per minute.

💭 Think About

• From the data sheet, what is the stroke of this engine, and how many stroke lengths does the piston travel in one crankshaft revolution? • Once you write the piston-speed formula using stroke (in feet) and RPM, what numerical value do you obtain when you substitute 21 inches and 400 RPM? • After calculating, which answer choice is closest to your computed feet-per-minute value?

✅ Before You Answer

• Verify that you used 21-inch stroke and converted it correctly to feet before multiplying. • Confirm that your formula includes the factor of 2 × stroke × RPM for a four-stroke piston’s round trip each revolution. • Double‑check the final units are feet per minute (ft/min) before comparing with the answer choices.
