Every machine is designed different. By mechanical leverage I mean that most machines do not lift or pull straight up or down. They have leverage built into the design, either by simply pushing/pulling at an angle, as in a front end loader, or by compound leverage in the way the cylinder lifts the machine, as in the bucket of a loader where the bucket itself is attached to a secondary arm at a different place than the cylinder, thereby compounding the force.
After working in an experimental hydraulics labratory for 25 years, I had to learn a little something about "leverage" in using a cylinder to move an object. "Bellcranks" are another place... one side of the crank is 6" long and the other is 8" long... it changes how much pressure and/or force it takes and how much movement you get from side to side. Many machines use different angles and different lengths of linkage, which changes the force required to move it.
