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 .
Therefore, if the cord moves with linear acceleration \texttip{a}{a} , the pulley must rotate with angular acceleration \large{\alpha=\frac{a}{R}} , where \texttip{R}{R} is the radius of the pulley. ANSWER: Correct Part B The acceleration of the blocks is zero. The net torque on the pulley is zero. The angular acceleration of the pulley is nonzero.
