Expert Solution
Step 1
21
Explanation:
In a gear train, the compound gears are the gears which are mounted on the same shaft. As compound gears are mounted on the same shaft, then they will have same angular speed. So, in the speed ratios, take equal speeds of compounded gears to determine the rotations of the gears. The example of the compound gear train is shown below:
Here, gears B and C are compounded on the same shaft. Thus, the rotation of gears B and C are same.
