Mean piston speed is a critical mechanical stress indicator.
It sets limits on valve timing, bearing loads and material fatigue.
Most production engines keep mean piston speed under 15 m/s; racing engines push this toward 25 m/s.
Given stroke S (m) and engine speed n (RPM), compute mean piston speed v_p (m/s).
