In a medium sized truck transmission, a 26-tooth clutch-stem helix gear meshes continuously with a 45-tooth countershaft gear. the data indicates a normal diametral pitch of 7.6 teeth/in, 18.5 degree normal pressure angle, 25 degree helix angle, and a 2.12in face width. the clutch-stem gear and the countershaft gear are cut with a right-hand helix. determine the normal and total contact ratios if the teeth are cut full-depth with respect to the normal diametral pitch.
