OK. Makes sense.

I assume this is a typo and you meant the integral of net force times piston displacement.

Nope :) Energy=integral( power) and power= F*V

My bad; I forgot you were integrating with respect to time.

E = integral(F(t)*V(t)*dt)

but also

E = integral(F(x)*dx)

Re: Optimizing Precharged Cylinders

From reading through this thread and the conclusions of preloading the cylinder 1/3 (or so) - does this mean 1/3 of the stroke is deployed (having approx. 1/3 of compressed air in cylinder) OR ...

Does this mean 2/3 of the stroke is deployed (having 2/3 compressed air in cylinder)?

Re: Optimizing Precharged Cylinders

Does anyone know if it is illegal to use a cylinder where you are not utilizing the full stroke distance? For instance using a cylinder with 10" stroke to unlock something where the movement distance is only 2" or so.
