The lengths of the links comply with the condition: K͞N:E͞K=M͞F:F͞E. When the platform is loaded, beam 1 is deflected from the horizontal position. A state of equilibrium is achieved by moving weight G along beam 1. Then weight G is related to the weight Q of the load being weighed by the equation G=Q(E͞F/L͞E)(B͞C/A͞C). The lengths of the links are designed so that for the maximum arm length A͞B, the product (E͞F/L͞E)×(B͞C/A͞C) equals 10 or 100 (decimal or centesimal scales).
