Thanks and @JurekB
surprising how tough a little 15mm cylinder is, rated up to 400N apparently and I think with a little re-rig I should be able to tuck them out of sight.
Unless I've conpletely misjudged the forces at play here:
roughly 17kg of top = about 170N
3:7 lever ratio
= about 400N split between 2 pistons?
Polygon
I'm thinking about using a pair of springs to counterbalance a fold down desktop in a bureau I'm designing. Is the force required to extend a spring, generally speaking, linear? Obviously the table is going from vertical to horizontal so I imagine the ideal counterbalance force would ramp up quite considerably at the end of its extension. Table will be about 18kg. Any other systems I should be looking at (pulleys and balances etc.)?
