Hi I'm trying to balance any 3d system with various fixed weights by selecting the correct lift forces for points of lift an example system would be the following shape ( view from above , think a plane missing the right wing) where X is a point of weight and L is a lift point (also has weight)
[X1][X2][L1][X4][L2]
to be clear
X’s are fixed weights
L’s can have variable lift forces
L3 needs to counteract the rotation from its own weight and the weight of X3
L1 is mostly central along the main body so will can counter X1,2,4 and L2's weight
L2 may not be needed
so something like L3 = 2(cancelling its and X3 weight / moment), L1 = 5 (cancelling the main body’s weight) L2 = 0 else it would flip
This is just an arbitrary shape, I need to be able to solve it for any number of lifts / weights in any shape / positions.
I’m sure I learned how to solve this sort of problem during my degree however I guess I can’t find the correct set of words to put into the all-knowing google!
Any help would be appreciated!
