I'm not an engineer ... but my first degree was in applied mathematics, Inmate51.
As such, my approach is to move from the simplest case ... to more complex cases. You asked what is my situation:
* the simplest case (of my situation) is ... I'm interested in the apportioning of the weight of a bearing & platter which is located somewhere inside a right-angled triangle, on 3 springs which are fixed at the apexes of said triangle.
The "3-pointed star" comes from there being 3 (imaginary) arms of the 'star' which connects the central bearing location to the 3 springs.
The desired result is to get the weight of the bearing & platter apportioned equally, so that the 3 springs are equally compressed.
Hence my statement to ignore the weight of the (imaginary) 'star'.
* the more complex case is then to account for the weights of 2 arms which are located just off-board of 2 of the springs.

Andy
