Q3:- A pinion of 20 teeth is in mesh with an internally toothed wheel with 80 teeth. The teeth have involute profile with pressure angle of 20° and the module is 5 mm. The addendum on the wheel is as large as possible to avoid interference and the contact ratio is to be 2.0. Find the addendum length of the wheel and pinion.
