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 ...
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 balance spring is a fine spiral or helical torsion spring used in mechanical watches, alarm clocks, kitchen timers, marine chronometers, and other timekeeping mechanisms to control the rate of oscillation of the balance wheel. The balance spring is an essential adjunct to the balance wheel, causing it to oscillate back and forth. The ...

The English Springer Spaniel field-bred dogs tend to have shorter, coarser coats than show-bred dogs. The ears are less pendulous. Field-bred dogs are wiry and have more of a feral look than those bred for showing. The tail of the field-bred dog may be docked a few inches in comparison to the show dog.
An inertial balance is a device that allows the measurement of inertial mass (as opposed to gravitational mass for a regular balance) that can be operated in the microgravity environment space where weight is negligible (e.g. in the International Space Station.) The principle of operation is based on a vibrating spring-mass system.
