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 ...
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.
Before using triple beam balance, the scale pointer should be at zero. The zero adjustment knob can be used to adjust the scale pointer. The objects are placed on the pan and the riders are adjusted. The hundred rider should be initially adjusted and follow by the tens rider. The ones rider is adjusted until the scale pointer is at zero again.
A sieve analysis (or gradation test) is a practice or procedure used in geology, civil engineering, and chemical engineering to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the ...
Mass balance. In physics, a mass balance, also called a material balance, is an application of conservation of mass [1] to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique.
The Kibble balance is a more accurate version of the ampere balance, an early current measuring instrument in which the force between two current-carrying coils of wire is measured and then used to calculate the magnitude of the current. The Kibble balance operates in the opposite sense; the current in the coils set very precisely by the Planck ...
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.
Jolly balance. The Jolly balance is an instrument for determining specific gravities. Invented by the German physicist Philipp von Jolly in 1864, [1] it consists of a spring fastened at the top to a movable arm. At the lower end, the spring is provided with two small pans, one suspended beneath the other. The lower pan is kept immersed to the ...
