Hi all, I'm having some trouble understanding a multi-spring system. Say I have 3 fixed nodes located at the following points in a 2D coordinate system: node1: (2,4) node2: (12,18) node3: (30,6) I have another node, node4, that is not fixed. Then I connect node4 to all three fixed nodes using springs. The spring constants are as follows. node4-node1: k1 node4-node2: k2 node4-node3: k3 My end goal is to determine the placement (coordinates) of node4, such that all the spring forces balance. i.e. F_total = 0 = F1_4 + F2_4 + F3_4 How can I go about solving (or approximating) for the (x,y) coordinates of node4 such that the forces (or energy) of the system sums to zero?
