Ross Crawford's utterance expressed in news:HJovou.1wF6@lugnet.com:


And thanks Kevin for the PPT file, it's great!

Definately - with more presentations like this - a whole
library of good knowledge can be made  :)

Although I do have one little query - on page 4, you say the cylinders
"Expand faster than they contract" - is this correct? I thought it
would be the other way round - they contract faster but with less
force?

you're right.. the volume to fill with air is smaller in the shaft-end
hence it moves faster inwards.. but that is without load.. I believe
that the force generated with LEGO-pneumatic is much greater in con-
traction than it is in expansion. But that is to be tested  :)

Play on...
