[PSUBS-MAILIST] new submarine

[hank pronk]

Scott,
I think know what your up to and it is a good idea.  You can use a longer stroke cylinder inside the sub with a smaller bore.  That gives you more power, you could actually have four foot pedals like brakes in your car to operate an arm.

 I
 have a question maybe someone can answer.
 If you have two hydraulic cylinders that are completely
 filled with oil (no air pockets anywhere in the system) one
 in a submarine and on outside of a submarine. Each cylinder
 has the rod side connected to the head side of the other
 cylinder so when on rod extends, the flow of one makes the
 other cylinder do the same exact thing. Would the one
 cylinder that does the same as the other cylinder on the
 surface function the same way at depth? Or would the deeper
 you go the more force you would have trying to push the rod
 into the cylinder? 
  
 Thanks,
 Scott Waters
