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).
There must be net torque which is responsible for starting the rotation of the pulley. The net torque is resultant of two torques due to the two cords. Tensions in left and right cords are NOT EQUAl . Tension in right cord is more because of the heavier mass of block B. The blocks move with acceleration and pulley has angular acceleration .
