How can I calculate the braking point or failure force of a 3" round structural tube with a 1/4" wall thickness and 20' long. What kind of force and amount would it take to twist it until it snapped??

You need to know more about the material used.

And maybe you could tell more about this case? You wrote "Twist", did I understand properly "torsion"? Or is it traction, bending, or maybe compression with buckling?
