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 .
Summary. Torque is the twisting force that tends to cause rotation. The point where the object rotates is known as the axis of rotation. Mathematically torque can be written as T = F * r * sin(theta) , and it has units of Newton-meters. When the sum of all torques acting on an object equals zero it is in rotational equilibrium.
