Homework Help: Gear train question.

  1. Sep 18, 2011 #1
    Good day folks,

    I hope someone can help me.

    How do I calculate w(1) without a w(arm)? There is no fixed gear, so no w(gear) = 0 as per normal, which has me baffled.

    Also - how do I calculate the overall gear ratio?

    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
