When ''Physical qty.'' = '''Torque''', the setting ''Coef.'' appears. It is the torsional stiffness of the shaft and it must be entered in '''N·m per radian''' (N·m/rad), not in N·m per degree. NVGate does not display this unit. | |||

* If the stiffness is known in N·m/°, multiply it by 57.3 (180/π). Example: 5000 N·m/° → enter ''Coef.'' = 286 479. | |||
* Example measured on the bench: twist 5.5° (= 0.096 rad) with ''Coef.'' = 1000 → torque = 96 N·m (and not 5500 N·m). | |||
* The ''Offset'' is an angle (in °), added to the twist '''before''' the coefficient: Torque = Coef. × (twist + Offset). | |||
