Node force balance determines tensions in a tensioned string network

Evidence

The relative tensions in the various line segments can be worked out from their geometry, and the rule that the force at each node (node here referring to places where the strings are tied together) must vanish. If this were not so, the node would accelerate according to Newton’s second law. — Eric J. Heller, Why You Hear What You Hear- An…, 1354
