the forces on the table act on a ring but are said to be concurrent. if the cords were rigidly to the ring would the forces necessarily be concurrent??

• physics -

Concurrent forces pass through the same point. Three forces that are in equilibrium must be concurrent. (Otherwise, there will be an unbalanced moment about some point where two intersect).
