The gear train shown below is used to lift the weight "W", which is equal to 1000 N of force. "A" can be considered a pully with a diameter of 50cm. "B" is a spur gear with 16 teeth, "C" is a spur gear with 38 teeth, "D" is a spur gear mounted to "C" (C and D turn together) and has 16 teeth, "F" is another spur gear with 38 teeth, and finally, "G" is a pulley mounted to gear "F" (has the same motion) with a diameter of 25cm. a) What is the overall gear ratio from input (A) side of the gear train to the output side of the gear train (G)? b) How much force does the hand need to supply in the downward direction to maintain a constant speed of the weight (no acceleration)?
