I'm trying to determine the force in tons of a hydraulic cylinder. Being mathematically challenged, even having a formula would be like reading Chinese to me. The cylinder has an outer diameter of 3.5", the shaft is 2", as best I can figure from information derived from the net, the bore would be 3". It has a stroke of 18". It will be fed from a pump delivering 8 GPM @ 2100 PSI.
Any help would be appreciated
