How to make a program and check how much heavy the helix bench can support?

Hello everyone:

How to make a program by using the karamba and check how much load the helix bench can support? It's mean that how much weight it will be broken?

This is titanium 6mm thick 150mm wide.

I uploaded the schematic diagram and the program. 

I don't know it is right or not?

Please help me check it?

Thank you very much.
