I am designing a gear train for my basic mechanisms class that consists of three shafts. The input horsepower is 10 and rpm is 1750. I calculated the torque of the first shaft to be 360 but I am not sure if the horsepower stays the same throughout the whole train or not. The first shaft has a 14t gear meshing witha 40t gear on shaft two. Shaft two then has a 22t gear meshing with a 48t gear on shaft three for an output rpm of 281. In order to calculate the torque and force per tooth of each gear do I just use the input horsepower? Thanks in advance for any help.
