What is the beam scale?

The balancing beam is a type of scale that uses a system of sliding weights that move on graded rays. The lever system connects the beam assembly with a pad where an object to be considered is located. The beam set has an indicator at one end, which is concentrated on a fixed point or holder with proper balance. By gradual adjustment of the sliding weights on the beams, the indicator can be centered and the weight of the object can be determined by reading the marks on the beams.

The digital age has made very accurate digital scales available, which have become more accessible in recent years. However, the balancing beam scale is still common, as they can also be very accurate; Some models will measure weights at the level of accuracy of two or three decimal places. They are purely mechanical and do not need a source of energy.

The basic design of the beam balance reaches back the century. These types of scale are derived from simple balancing scales, first known, for example,that date back to approximately 2000 B.C. These scales consist of a single beam supported in its exact center with a pelvis suspended from every end. The item to be considered is located in one pelvis and objects with known weight are added to the other pelvis until the scale is balanced.

Many doctors use the scale of balancing rays. This type of beam balance scale is designed to weighed a person in a pan. Sliding weights are treated on the rays until the indicator in the center of the holder becomes stable and the subject matter is read on the beams. The configuration is slightly different from the model peak models, but the general design and operation of both types is the same. The beam of the table balance is a common tool in classes, laboratories, test offices, jewelry shops and pharmacies.

The balancing beam scale measures the weight of the object rather than its weight. DiffeRence is negligible on the Earth's surface and both terms are usually used interchangeably without confusion. However, if someone should weigh per month, their weight would be approximately one six of their weight on the ground. The measure of the beam balance would bring the same result both places.
