Torsion wire device with filaments comprises a hollow body on its symmetrical axis, which is in rotation around the body and having two openings in its periphery, where the openings maintains the rotation

摘要

The filaments are placed between two fixed points by linear displacement. The axis is perpendicular to the symmetry of the device. A wire blocked in rotation is introduced within the body of torsion by its periphery and the rotation is maintained by the openings is compared to the scale machine.
