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).
For any torque, the force exerted is dependent on the leverage arm length. In our example the front sprocket diameter is 3.5. The radius is 1.75 or .145 ft. Dividing 125ft/lb of torque by the front sprocket radius of .145ft. yields approximately 850 lbs of potential chain tension (125/.145 = 850).Since the rear tire typically slips in second gear, it is apparent that tire traction cannot contain all the available engine torque.or any torque, the force exerted is dependent on the leverage arm length.
