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.
Apply torque to a bolt head only when a torque wrench cannot be used on the nut. After application of torque to a nut, further tightening to align the slot for cotter pin or lockwire is permitted. a. Torque Definitions. Torque definitions are explained In the following paragraphs. (1) Breakaway torque Breakaway torque (table 2-8) is defined as minimum torque required to start the movement of a nut on or off bolt with no axial load on the nut and with the bolt completely through the nut. (2) Friction torque (tare, drag, run on).
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.
