Design a nonreverted compound transmission based on the arrangement shown in Figure 12-14a for an overall train ratio of approximately 90:1.

1.       Design a nonreverted compound transmission based on the arrangement shown in Figure 12-14for an overall train ratio of approximately 90:1. It should be capable of transmitting 50 hp at 1 000 rpm input shaft speed. State all assumptions.

2.       Design a reverted compound transmission based on the arrangement shown in Figure 12-14for an overall train ratio of approximately 80:1. It should be capable of transmitting 30 hp at 1 500 rpm input shaft speed. State all assumptions.

3.       If the 23-tooth pinion in the gearset in Problem 12-3 is on the input shaft, find the velocity ratio, torque ratio, and gear ratio for the gearset.

4.       If the 78-tooth gear in the gearset in Problem 12-4 is on the input shaft, find the velocity ratio, torque ratio, and gear ratio for the gearset.
