1. The problem statement, all variables and given/known data Four T-shaped objects are constructed by connecting two identical rods of equal mass and equal length. Rank in order, from LARGEST to SMALLEST, the moments of inertia for rotation about the axis indicated by the dashed line. 2. Relevant equations 3. The attempt at a solution For the first, I used parallel axis theorem for the rod lenght l away, and for the rod perpendicular to the axis, I took its MI as m*l^2/3. I'm pretty sure that's a wrong approach. I need someone to point out how to go about this.
