The balance (also balance scale, beam balance and laboratory balance) was the first mass measuring instrument invented. [1] In its traditional form, it consists of a pivoted horizontal lever with arms of equal length – the beam or tron – and a weighing pan [ 10 ] suspended from each arm (hence the plural name " scales " for a weighing ...
A bascule bridge (also referred to as a drawbridge or a lifting bridge) is a moveable bridge with a counterweight that continuously balances a span, or leaf, throughout its upward swing to provide clearance for boat traffic. It may be single- or double-leafed. The name comes from the French term for balance scale, which employs the same principle.
A Roberval balance shown responding to two masses of equal weight. The Roberval balance is a weighing scale presented to the French Academy of Sciences by the French mathematician Gilles Personne de Roberval in 1669. In this scale, two identical horizontal beams are attached, one directly above the other, to a vertical column, which is attached ...
Spring scale. A spring scale, spring balance or newton meter is a type of mechanical force gauge or weighing scale. It consists of a spring fixed at one end with a hook to attach an object at the other. [1] It works in accordance with Hooke's Law, which states that the force needed to extend or compress a spring by some distance scales linearly ...
A balance puzzle or weighing puzzle is a logic puzzle about balancing items—often coins—to determine which holds a different value, by using balance scales a limited number of times. These differ from puzzles that assign weights to items, in that only the relative mass of these items is relevant. Known. Goal.
Archangel Michael is commonly depicted holding scales to weigh the souls of people on Judgement Day. The weighing of souls ( Ancient Greek: psychostasia) [1] is a religious motif in which a person's life is assessed by weighing their soul (or some other part of them) immediately before or after death in order to judge their fate.

The scales were held sacred to the sun god Shamash, who was also the patron of truth and justice.
Synonyms. BBS. Purpose. test of a person's static and dynamic balance abilities. The Berg Balance Scale (or BBS) is a widely used clinical test of a person's static and dynamic balance abilities, [ 1] named after Katherine Berg, one of the developers. [ 2] For functional balance tests, the BBS is generally considered to be the gold standard.
