Example Solution for Equivalent Inertia

posted Feb 6, 2015, 3:17 PM by Nate Delson   [ updated Feb 6, 2015, 5:12 PM ]

Questions were raised on how equivalent inertia is calculated and how gear ratios effect this. Specifically, the question asked is why inertia is multiplied by the gear ratio squared. The answer is determined by going through the Free Body DIagrams, like we did for the mass raising a pulley problem in week 1. For guidance, I just posted a solution with 2 rotary motions, which is closer to the problem that the class is working on. The solution file is: "Rotary-Dynamics-Solution.pdf" in Assignments.

I have recived some question about the HW. I welcome questions but note that the answers are in the Lectures and the reference links at the bottom of the HW.
