Summary

Description
English: Diagram of an Equal-armed Balance: D is the fulcrum of the balance, S the centre of gravity of the beam alone without the scales, chains or weights; A and B the points of suspension of the chains. The length of the arms AC = BC = l, CD = a, the angle of deviation of the balance from the horizontal = φ, the weight of the beam alone = G, the weight on one side = P, that on the other = P + Z, and lastly the weight of each scale with its appurtenances = Q.
