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 .
Depending on the nature of the machinery and the types of bearings used the breakaway torque can be anywhere from 120% to 600% and above of running torque. The table below provides some typical ranges: Running torque is the torque that is required to sustain the machine at the normal operating rotational speeds.
