The two main levers end at a plate that houses the scale's main spring. Here you can see why a 1:12 ratio is used in the scale - it significantly reduces the size of the spring. The spring only has to be able to support 20 or so pounds. Without the levers, the spring would have to support 240 pounds, and it would have to be much bigger to do that.

How Do Weighing Scales Work? Bathroom scales utilize a series of levers to distribute weight evenly while placing tension on a spring connected to a dial. The spring is calibrated so that it elongates under force, turning the attached dial until it displays a number proportionate to the weight distributed by each lever.

A scale displays weight by measuring a deflection; the springs are deformed by the load, and the force needed to deform the springs is measured, and converted into weight. Mechanical Scales. A hook, spring or hanging scale operates on a principle based on Hooke's Law. It states that "the force exerted on a spring is directly proportional to the ...
