On the internet they list ways to calculate weights based on CG when there is a weight on the left and on the right of your CG.
Most of the examples show a box truck for determining the weight on the axles.
How would you determine weight when there are 3 points rather than two. I tried looking up how to determine the weights on the axles of a semi-tractor and trailer, but the weight of the front axle seems to always be known.
I would like to suspend this load using springs. So points A, B, and C would be springs in this case. How can I determine the weight on each spring?
The internet seems to have almost nothing beyond the simple A/B example.
