Does the number of strokes in a telescoping piston affect the power delivered? Is there a way to "compound" the effect, as in steam compounding? Trekphiler 03:20, 19 August 2007 (UTC)

Compound steam engines make use of the expansive property of steam. As hydraulic fluid expands very little, there would be no point in using compounding in a hydraulic machine. Biscuittin (talk) 21:17, 4 February 2008 (UTC)
I'm thinking less of the expansion than the ability to shorten the piston stroke by "nesting" pistons; does this multiply the power? Or make no difference? Trekphiler (talk) 22:07, 4 February 2008 (UTC)

I think you are talking about force, rather than power. Whether "nesting" pistons multiplies the force, I'm not sure. Can anyone else help? Biscuittin (talk) 17:45, 5 February 2008 (UTC)

"talking about force"? Very possibly, seeing how ignorant I am of physics... Trekphiler (talk) 21:08, 5 February 2008 (UTC)

If I were designing a hydraulic machine, I would decide how much force I needed and then select the piston size to match. I think the reason for using telescoping pistons is not to multiply the force but to save space. A telescoping piston, when closed, will be much shorter than a single one. However, I'm not a physicist and I could be wrong. Biscuittin (talk) 09:07, 6 February 2008 (UTC)

That's my thinking: if I've only got "x" space, how much is the max output I can deliver? Trekphiler (talk) 22:58, 6 February 2008 (UTC)
