The balance wheel and spring function similarly to the torsion pendulum above in keeping time for the watch. The D'Arsonval movement used in mechanical pointer-type meters to measure electric current is a type of torsion balance (see below). A coil of wire attached to the pointer twists in a magnetic field against the resistance of a torsion ...
Sectional garage door Up-and-over garage door Garage Door Hardware. A garage door is a large door to allow egress for a garage that opens either manually or by an electric motor (a garage door opener). Garage doors are frequently large enough to accommodate automobiles and other vehicles. The operating mechanism is usually spring-loaded or ...
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 diameter of the barrel is related to the mainspring length and strength, but this method for determining strength only works for springs of standard lengths.) Each manufacturer used a different arbitrary scale to describe mainspring sizes, but these sizes are usually based on the French inch. Figure 2: Martin mainspring slit gauge.
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.
