Problem 2: A 30-tooth pinion drives a 128-tooth gear. Given a diametral pitch of 16 and a pressure angle of 25, find the contact ratio. How does this ratio compare to the recommended contact ratio? Step 1: Calculate p, p, CD, and the addendum. Ip1 = Step 2: Find the contact ratio. Tp = mp = Step 3: Circle the correct statement below. CD = a) This gear pair has an unacceptable contact ratio. b) This gear pair has an acceptable contact ratio. a =
