Gear's Torque (small to big) and (big to big)

  1. Oct 23, 2009 #1
    Hello
    so here is the problem that I'm confused with:
    let's say....

    Will a torque produced by a 20 teeth(force is exerted to this one) to 60 teeth gear be the same torque compared to a 60 teeth(force is exerted to this one) to a 60 teeth gear.

    My torque is infinite, my friend.

    Calculate the effective radius of the contact points on the theeth of the two gears, and use your knowledge of lever arms.
