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.
Breakaway torque is defined as the torque required to start a partâs rotation from a stationary position. It is usually a higher value compared to the maximum tightening torque value as per specification .
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.
