      Any wat in which 1 and 3 are not in contact with each other. Lines work. 2 being double thickness and 1 and 3 having depth separation works.

      Gears are really simple and absolutely something more people should understand

            I wish I was an engineer, but I have read a few mechanical engineering books with chapters on gears, and it really is a bottomless pit.

            In the example, I recall seeing a method a ways back where 3 interlaced gears could rotate simultaneously. Two are linked traditionally, while one is a helical gear that slides though the teeth of the other two. It had a slick animation, wish I could find it.

        Nothing is more simple than American’s, I’m afraid. We’ve been losing a war on education for around 70 years now.

      Making the 2 smaller ones not touch each other or one of the small ones not touching with the big one would do it

      I can’t find that picture (it was anothet textbook cover probably) but imagine the students gear as a long cylindrical gear, and the two other as shorter gears, so when you move say the parents gear it would move the students gear and that in turn will move the teachers gear and it would look fine from the side but looks impossible from the front
