Wow. Did you do that for a paper or thesis? Very worthy research with a surprising outcome. I am sure most of us would surmise that the big sprung cylinder would give more efficacious designs because the displacement would be larger. This site (...)

Dave, You state in your documentation that * / and % can be used on constants only, but your example has x * Y in it. What is it that you mean?
