I checked McMaster-Carr to find example of torsion springs that have the same wire diameter but different number of turns but couldn't find any . talk ) 10 : 39, 15 April 2016 ( UTC)

I'd think that a torsion spring could be rigged up to drive a small dynamo, and the resulting current could either run a device directly, or charge its battery, or perhaps even both, depending on needs.

The complexity of construction and in particular the torsion springs ( which the Romans referred to as " tormenta " ) led to great sensitivity to any variation in temperature or moisture, which limited their use.

As the user applies manual pressure to the thumbstud to open the knife, a mechanism such as a torsion spring moves along a track in the liner and rapidly rotates the blade into the open and locked position.

This included replacing the remaining wooden parts of the machine with metal, creating a much smaller, lighter and more powerful machine than the wooden version, which required less maintenance ( though the vital torsion springs were still vulnerable to the strain ).

The slider passed through the " field frames " of the weapon, in which were located the " torsion springs " ( rope made of animal sinew ), which were twisted around the bow arms, which in turn, were attached to the bowstring.
47.
In contrast, a spring-assist design uses manual pressure on a lever or switch mounted on the blade or connected via a direct mechanical linkage to open the blade initially, at which point an internal torsion spring propels the blade into an open, locked position.

A "'mainspring "'is a spiral torsion spring of metal ribbon-commonly spring steel-used as a power source in mechanical watches, some clocks, and other clockwork mechanisms . " Winding " the timepiece, by turning a knob or key, stores energy in the mainspring by twisting the spiral tighter.

This mechanical arming is accomplished by a torsion spring rotating the detonators 180 degrees into an explosive train alignment as soon as the spring is unlocked by the acceleration forces depressing a Zig-Zag Setback Device ( Figure 3 ) and the wind stream forces unscrewing a Jackscrew ( Figure 4 ) locking device.

Instead, most of door's weight is offset by the counterbalance springs attached to the door . ( Even manually operated garage doors have counterbalances; otherwise they would be too heavy for a person to open or close them . ) In a typical design, torsion springs apply torque to a shaft, and that shaft applies a force to the garage door via steel counterbalance cables.
