**Damon**, Saturday, November 3, 2012 at 10:26pmObviously I do not know what your axes are.

lengths 2 and 1

masses 2 and 1

if along the long rod:

I = (1/3)(1) * 1^2 = 1/3

if along the short rod

I = (1/12)(2) * 2^2 = 8/12 = 2/3

if perpendicular to the plane of the rods at intersection

I = 3 (1/3) (1)(1^2) = 1 = 3/3

so angular accelerations are in the ratio 1,2,3 with the maximum being along the long rod through its center and the minimum (max I) being the last of the three
