In the gear train shown below the input gear 2 rotates at $2400\mathrm{rpm}$, and gears 3 and 4 are rigidly connected. The pitch diameters are as shown on the diagram. Determine (a) the train value for this gear train, (b) speed and direction of rotation of the output gear 7 , and (c) the center distance between gears 2 and 7 Assume that the lines through the top three shafts and the lower two shafts are parallel. State whatever other assumptions you need/ or are making to solve this problem.
