1. The problem statement, all variables and given/known data You are given a meter stick and asked to drill a hole in it so that when pivoted about the hole the period of the pendulum will be a minimum. Where should you drill the hole 2. Relevant equations T=2*pi*sqrt(I/mgd) 3. The attempt at a solution So I use parallel axis theorem for I and get I=I(com)+mh^2=(1/12)mL^2+mh^2 = m*((1/12)+h^2) because L=1 as in a meter stick. Plug in the formula I have T= 2*pi * sqrt( (1/12)+h^2 / gh) because m cancels out and d=h because h is the distance from center of mass. How should I move one to get the final answer ???
