- Homework Statement
- Calculate the moment of inertia of 2 uniform thin rods about axis A where the figure belows shows the top view.

- Relevant Equations
- ##I=\frac{1}{12}ml^2##

So to start off, what I will do find the center of mass of each of the rods. So for the top rod, COM is at where y= 0.5 L and COM of the rod at the bottom is at x = 0.5 L. From there, how do I proceed in finding the moment of inertia using parallel axis theorem? Do I simply treat:

##I =\frac{1}{12}ml^2+md^2##

Where d is the distance between the centre of mass and point A for each of the rods respectively? (Whereby d will be 0.5 L - 4/9 L for the bottom rod)

Thanks
