Can someone please help me understand what this means?: "And therefore if weight 'p' is to weight 'A' in a ratio compounded of the reciprocal ratio of the least distances of the chords PN, AM, from the center of the wheel, and of the direct ratio of pH to pN, the weights will have the same effect towards moving the wheel and will therefore sustain each other." I am totally confused. Tell me if this is insufficient to answer my question. Thanks for any responses.
