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 .
The following important conclusions can be drawn from the above equation. 1  Two alternating fluxes with a phase shift are needed for torque production. 2  Maximum torque is produced when the two alternating fluxes are 90 degrees apart. 3  The resultant torque is steady and not a function of time.
