Hi all,
I am trying to develop a revolved shape that will have a known mass = 130 kg and known I (about the rotation axis) = 3.6e7 kg*mm^2 and must fit inside the cylinder with Do <= ~1200 mm, Di >= ~300 mm and Length < 450 mm.
Shape is completely arbitrary and density can be modified as well. I tried many obvious shapes and can not get the inertia high enough with the variables I have. Any suggestions? I am using Pro/ENGINEER's Behavioral Modeling functionality, but the problem solution is not dependant on this tool.
Thanks in advance.
Best regards,
Matthew Ian Loew
