Noob: analysis of forces (by Alexander)
Sorry for posting as a total newbie:
I've scetched a springless relax chair that shall balance over wide reclining angles, like a rocker. Attached is one of several versions; details don't matter yet.
I need analysis of
a) Center of gravity (with weights simulating body parts): potential energy curve on Y-axis during backrest movement.
b) Horizontal CoG position during backrest movement.
c) Forces on joints (could be thousands of Newtons due to levers).
Any program to import geometry and compute this for iterative curve optimization? Coding this myself is way beyond my abilities.
Any first step recommendation? Please no "study your math" – too old/dumb for that.
Thanks!

If you have a 3D model you can go in the Analyze menu and select Measure Volume, which you could multiply by your material density to get mass. You can also use Show Center of Mass to get the coordinates of the CG. That's about as far as Solvespace will take you with what you're doing. For analyzing stress under load, you can export a .STEP file and use an FEA program like gmsh or similar.
