QUESTION 1 Input Output An epicyclic gear train is shown schematically in the figure. The sun gear D on the output shaft is a 40 teeth external gear. The planet gear B is a 20 teeth external gear. The annular gear C is fixed and has internal gear. The Arm A connected with input shaft is rotating at 60 rpm ccw (ccw-counter-clockwise and cw =clockwise) with input power of 16 KW. The efficiency of the gear system is 94%. Find (10) 1.1 the speed and direction of the sun gear attached to the output shaft. (6) 1.2 the output torque and the torque required to hold the annular gear fixed. [16] Arm
