3) The gearbox is to be designed with a compound gear train. It is needed to minimize the overall gearbox size and avoid the interference problem in teeth. For this gearbox; a) Calculate appropriate teeth numbers for each gear to provide an 40:1 (+2% tolerance) increase in speed. b) Calculate appropriate teeth numbers for each gear to provide an exact 40:1 increase in speed. Given Data: k-1, pressure angle (6)-25
