Guys, I'm trying to figure some stuff out, but I'm stumped. I need to figure the what my output would be. I'm applying linear force via hydraulic cylinder. The cylinder will turn a "gear" and in turn turn another. The "gear" is not necessarily a gear, it and the hydraulic cylinder will mate with each stroke of the cylinder. It will push it to be simple. The "gear" will mesh with the other final gear. "gear" = 2" "final" = 3" Single Acting Cylinder Cylinder surface area = 3" Cylinder Stroke = 0.75" Hydraulic Pump Pressure = 10,000psi max Pump flow = 60 in3/min Pump HP = 1.7 So I'd like to know what the max torque output would be @10,000psi. I'd also like to know how to figure this on my own. I know how to do a little bit, but I'm not even sure if I"m doing it correctly. I'm trying to teach myself this stuff, but all the places I'm looking aren't exactly related to my scenario. Thanks guys, any help is greatly appreciated!
