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 = 300 N-mm/rad and 9 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. Assume r = 50 mm, d = 100 mm. 45 d Answers: If 0 = 26%, the tension T = N If 0 = 48%, the tension T = N If 0 = 80%, the tension T = N i i i
