The scale is balanced when the torque provided by the patient’s weight (large force, small lever arm) balances the torque provided by the small weights (small mass, long lever arm).

Work Step by Step

The small sliding weights are relatively far from the pivot point (i.e., a long lever arm), but the platform on which the patient stands is attached very close to the pivot point (i.e., a short lever arm).
