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 with respect ...
The balance was made of wood and used bronze masses. ... In electronic versions of spring scales, ... containers, and other heavy-duty vehicles. They are used in ...
An example of an electrical force gauge is an "electronic scale". One or more electrical load cells (commonly referred to as "weigh bars") are used to support a vertical or horizontal "live load" and are solid-state potentiometers which have variable internal resistance proportional to the load they are subjected to and deflected by.
Helical coil springs designed for tension A heavy-duty coil spring designed for compression and tension The English longbow – a simple but very powerful spring made of yew, measuring 2 m (6 ft 7 in) long, with a 470 N (105 lbf) draw weight, with each limb functionally a cantilever spring. Force (F) vs extension (s).
Spring spikes or elastic rail spikes [25] are used with flat-bottomed rail, baseplates and wooden sleepers. The spring spike holds the rail down and prevents tipping and also secures the baseplate to the sleeper. [26] The Macbeth spike (trade name) is a two-pronged U-shaped staple-like spike bent so that it appears M-shaped when viewed from the ...
