Problem 01 Two gears are to be mounted 8 in. apart and have a velocity ratio of 2:1. Find the appropriate pitch diameters, diametral pitches, and the number of teeth on both gears that will be suitable. Problem 02 A pair of 20, mild-steel gears is to be selected for an application where they need to transfer 0.75 hp. The pinion drives at 1200 rpm and the gear must rotate as close to 400 rpm as possible. Determine an appropriate set of catalog gears for this application. You will need data from Tables 10.6 and 10.7 shown.
