These balance scales, made up essentially of a lever with identical arms, is a device used to measure the mass of an object in comparison with the weight of another object of a known mass.
What can be deduced from its use is that the weight hanging on different arms is equal to the inversion of the ratio of its distances to the support point.
These balance scales have been used for experimentation and demonstration for didactic purposes.
