Homework Help: Cubical block on a cylinder challenging problem

  1. May 28, 2012 #1
    1. The problem statement, all variables and given/known data
    A cubical block of side L rests on a fixed cylindrical drum of radius R. Find the largest value of L for which the block is stable.

    This is problem 6.35 from the Kleppner+Kolenkow Introduction to Mechanics book. I honestly have no clue where to even start on this problem. Anyone care to give me a hint?

    Say you displace the block by an angle θ. Where's the support point? Where's the center of mass in relation to the support point?
