  2. Triple beam balance - Wikipedia

    en.wikipedia.org/wiki/Triple_beam_balance

    Base - The base rests underneath the weighing pan and can usually be customized to fit on a workbench or set up with tripod legs. Beams - The three beams on the balance are used to set the level of precision, with each beam working at different increments (1-10 grams, 10 grams and 100 grams). When using the triple beam balance, it is ...

  3. Weighing scale - Wikipedia

    en.wikipedia.org/wiki/Weighing_scale

    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 instrument).

  4. Roberval balance - Wikipedia

    en.wikipedia.org/wiki/Roberval_Balance

    A Roberval balance made by W & T Avery Ltd. in England Detail: the bottom horizontal beam is hidden under the protective cover 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.

  5. Steelyard balance - Wikipedia

    en.wikipedia.org/wiki/Steelyard_balance

    Steelyard weighing device from the late nineteenth century. Minnesota Historical Society collections. Roman steelyard from Pompeii. The steelyard comprises a balance beam which is suspended from a lever/pivot or fulcrum which is very close to one end of the beam. The two parts of the beam which flank the pivot are the arms.

  6. Mass versus weight - Wikipedia

    en.wikipedia.org/wiki/Mass_versus_weight

    A balance-type weighing scale: Unaffected by the strength of gravity. Load-cell based bathroom scale: Affected by the strength of gravity. When one stands on a balance-beam-type scale at a doctor’s office, they are having their mass measured directly. This is because balances ("dual-pan" mass comparators) compare the gravitational force ...

  7. Decimal balance - Wikipedia

    en.wikipedia.org/wiki/Decimal_balance

    Old decimal balance scale A drawing to illustrate a design with two-point support of the platform. A decimal balance or decimal scale is a balance scale which uses the lever in which the arm for weights is 10 times longer than the arm for weighted objects, so that much lighter weights may be used to weigh heavy object. [1]

  8. Analytical balance - Wikipedia

    en.wikipedia.org/wiki/Analytical_balance

    An analytical balance (or chemical balance) is a class of balance designed to measure small mass in the sub-milligram range. The measuring pan of an analytical balance (0.1 mg resolution or better) is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation ...

  9. Weight - Wikipedia

    en.wikipedia.org/wiki/Weight

    In the operational definition, the weight of an object is the force measured by the operation of weighing it, which is the force it exerts on its support. [10] Since W is the downward force on the body by the centre of earth and there is no acceleration in the body, there exists an opposite and equal force by the support on the body. Also it is ...
