- The throttle-control lever OA rotates in the range 0 ≤ 0≤ 90°. An internal torsional return spring exerts a restoring moment about O given by M = K(0+1/4), where K= 440 N-mm/rad and is in radians. Determine and plot as a function of the tension T required to make the net moment about O zero. The effects of the radius of the pulley at B are negligible. After you have completed the plot. answer the questions.
