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).
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.hile often heard as an automotive term, torque is actually a general physics term that has many applications. Torque is defined as a twisting force that tends to cause rotation. We call the point where the object rotates the axis of rotation.
