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).
The parts of triple beam balance are identified as the following. [3]Weighing pan - The area in which an object is placed in order to be weighed.; Base - The base rests underneath the weighing pan and can usually be customized to fit on a workbench or set up with tripod legs.
A steelyard balance, steelyard, or stilyard is a straight-beam balance with arms of unequal length. It incorporates a counterweight which slides along the longer arm to counterbalance the load and indicate its weight. A steelyard is also known as a Roman steelyard or Roman balance. A 19th-century steelyard crane
Planar Beam load cells; used in low profile solutions where space is limited, like medical scales and retail scales. Bending Beam load cells; used in pallet, platform and small hopper scales. Shear Beam load cells; used in low profile scale and process applications, available in capacities from 100kg up to 50t.
Beams - The three beams on the balance are used to set the level of precision, with each beam working at different increments (generally 1-10 grams, 10 grams and 100 grams). When using the triple beam balance, it is recommended to start with the lowest level of precision (e.g. 100 gram increments) and then work your way down.
A simple crane. A counterweight is a weight that, by applying an opposite force, provides balance and stability of a mechanical system. [1] The purpose of a counterweight is to make lifting the load faster and more efficient, which saves energy and causes less wear and tear on the lifting machine.
Engine balance refers to how the inertial forces produced by moving parts in an internal combustion engine or steam engine are neutralised with counterweights and balance shafts, to prevent unpleasant and potentially damaging vibration. The strongest inertial forces occur at crankshaft speed (first-order forces) and balance is mandatory, while ...
The earlier single-action beam engines used a chain to connect the piston to the beam and this worked satisfactorily for pumping water from mines, etc. However, for rotary motion a linkage that works both in compression and tension provides a better design and allows a double-acting cylinder to be used. Such an engine incorporates a piston ...
