The pinion S (see FigQ3) has 15 teeth, and is connected to a motor shaft. The wheel P has 20 teeth and gears with S and also with a fixed annulus wheel A. The pinion C has 15 teeth and is fixed to the wheel P. C gears with the annular wheel D, which is keyed to output shaft. P and C can rotate together on a pin carried by an arm, which rotates about the shaft on which S is connected. [15] Compute the number of teeth on gear A and D. Find the speed of the output shaft if the motor rotates at 1000 rpm CW. Also find the holding torque required on wheel A if 5 kW is delivered to S. a A 10 S D FigQ3 S. A D
