REFLECTOR: Annual inspection/Compression Testing.

[mb]

Units need to be the same. PSI on square inches, or pounds per square millimeter with sq mm of the piston surface. Don't mix the units.

    There is nothing in your formula that quantifies the area over which the 
    1698 lbs. is spread.  Using your formula, I could say that the piston is 
    132mm in diameter in which case:

    13,701.4 sq mm @ 80psi=1,096,112 lbs. force

  5.2" diameter piston as given above by Dave.  Anyway, what's this mm stuff?? America is the strongest country on earth and we do things in inches and speak English! (can't you just hear John Wayne)?
