     In normal operation, the input cranks to both the MPCU and standby rudder actuator will rotate to provide the servo valve command to the units, and the rudder will be hydraulically moved by the MPCU. The rudder movement is in turn fed back mechanically to both the MPCU and standby actuator systems so that when the rudder surface deflects to the position commanded by the pilot, the input cranks on both of the units will be returned to their null positions. Thus, there is a geometric relationship between the rudder position, the input crank of the MPCU, the torque tube, and the input crank of the standby rudder actuator that is retained during normal operation.

2. To return to the null position, setting, etc.

     Three factors could ameliorate the effect of a bound input shaft and bearing. The first is the elasticity of the control system linkage that, against a definable load, will permit sufficient deformation of the otherwise rigid link feedback loop to null the MPCU servo valve. The second factor is the application of a load sufficient to break loose the binding between the input shaft and bearing. The third factor is a loss of torque of the bearing in the standby rudder actuator housing to permit the rotation of the bearing and shaft together within the housing to compensate for the bound shaft.

3. To form nulls, or into nulls, as in a lathe.
4. (computing, slang, transitive) To crack; to remove restrictions or limitations in (software).
