This patient had a recurvatum problem at the knee; so, the posterior shell might have been given to this patient to gain some time until the patient's knee flexors became stronger.
Apply torque to a bolt head only when a torque wrench cannot be used on the nut. After application of torque to a nut, further tightening to align the slot for cotter pin or lockwire is permitted. a. Torque Definitions. Torque definitions are explained In the following paragraphs. (1) Breakaway torque Breakaway torque (table 2-8) is defined as minimum torque required to start the movement of a nut on or off bolt with no axial load on the nut and with the bolt completely through the nut. (2) Friction torque (tare, drag, run on).
Power angle is also same in context of synchronous machines but it is more generic â also used in power transmission line. To explain what they are: Load angle (or Torque angle): For a synchronous generator, the magnetic field rotates at synchronous speed and the rotating magnetic field is created in the stator. But the fact is that Load angle or power angle is the angle between terminal voltage and excitation voltage. Torque angle is the angle between excitation field mmf and resultant air gap mmf....in a synchronous generator. The load angle and torque angles differ due to the presence of armature leakage emf.
