In an epicyclic gear train as shown in figure, pinion A has 15 teeth and is rigidly fixed to the motor shaft. Wheel B has 20 teeth and gears with A and fixed annular wheel D. Pinion C has 15 teeth and is integral with B (C – B being compound gear). Gear C meshes with annular wheel E, which is keyed to the machine shaft. The arm rotates about the same shaft on which A is fixed and carries the compound wheel B-C. If the motor runs at 1000 rpm, find the speed (in rpm) of the machine shaft.
Enter numerical value using the virtual keypad. Round off where necessary.
