I am trying to find out how much force is being transferred into a drive chain. Here's the info as I was given: Motor: 150HP RPM: 1750 Gearbox information: ratio: 39:44 Input HP 223 Output shaft to sprocket 6" dia. Sprocket 20" dia. Top of tooth to bottom of root 1-3/8" 4" pitch of chain No other sprockets connected. Am I correct in assuming there is some extraneous info in there? As in, the input HP on the gearbox, I think that's a max number they may have pulled off the id plate? What we're looking for is the tonnage of the bench.
