Use Matrices to solve a system of equations.
In this case a matrix for three equations (possibly differential equations).
Not too bad if you are only taking into account the three weights/distances/angles.
It will start to get complicated if you bring in spring rate change with compression, angle changes with weight shifts and other factors.
Should be a piece of cake for a first or second year math major.
I don't know how badly you need this but your local University can hook you up with a math or engineering major. A cash starved student may jump at a few bucks to set you up.
Sorry Andy, more than three decades since I've had to do serious math. I can feel a tickle buried in my brain that wants/needs to do this but there is just not enough left. Math not brain :-).

Haha - thank you for your input, DE.
I should have the maths to hand ... but I guess 45 years of alcohol since those days has depleted the brain cells. (Not including, in Dr Strangelove terms, the loss of essential bodily fluids! :-)) )
Regards,
Andy

Ah, you mean the Communist conspiracy to sap and impurify all of our precious bodily fluids!
