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 .
A torque is generated by a pair of forces, similar in magnitude, opposite in direction, and parallel to each other. These two forces are separated by a finite distance. In physics, the term moment also has the same meaning as torque.Torque is defined as the tendency of a force to rotate an object about an axis, a fulcrum, or a pivot. A torque can also be provided using a single force acting at a distance r from the axis of rotation. torque is generated by a pair of forces, similar in magnitude, opposite in direction, and parallel to each other. These two forces are separated by a finite distance. In physics, the term moment also has the same meaning as torque.
