The force required to hold the string stationary at full draw is often used to express the power of a bow, and is known as its draw weight, or weight. [ 36 ] [ 37 ] Other things being equal, a higher draw weight means a more powerful bow, which is able to project heavier arrows at the same velocity or the same arrow at a greater velocity.

Each pairing of a current measuring unit plus a potential measuring unit is then termed a stator or element. Thus, for example, a meter for a four wire service will include three elements. Blondel's Theorem simplifies the work of an electrical utility worker by specifying that an N wire service will be correctly measured by a N-1 element meter.
Estimates for the draw of these bows varies considerably. Before the recovery of the Mary Rose, Count M. Mildmay Stayner, Recorder of the British Long Bow Society, estimated the bows of the medieval period drew 90–110 pounds-force (400–490 newtons), maximum, and W. F. Paterson, Chairman of the Society of Archer-Antiquaries, believed the weapon had a supreme draw weight of only 80–90 lb f ...

The unit commitment problem (UC) in electrical power production is a large family of mathematical optimization problems where the production of a set of electrical generators is coordinated in order to achieve some common target, usually either matching the energy demand at minimum cost or maximizing revenue from electricity production.
Longbowmen archers of the Middle Ages.. Archery, or the use of bow and arrows, was probably developed in Africa by the later Middle Stone Age (approx. 70,000 years ago). It is documented as part of warfare and hunting from the classical period (where it figures in the mythologies of many cultures) [1] until the end of the 19th century, when bow and arrows was made functionally obsolete by the ...
