Beam balance with freely selectable suspension point

A beam balance uses a special mechanical arrangement with two axes of rotation, one above the other. When loaded, it does not produce a rotational movement, but rather a vertical linear offset. The deflection thus does not depend on the distance of the attached weight from the centre of the beam balance. This is similar to the action of a weighing machine with two weighing platforms, for which the measurement also does not depend on the position of the load on the weighing plate.
