A uniform rectangular coil of total mass 270 g and dimensions 1m x 5m is oriented perpendicular to a uniform 4.00-T magnetic field (the figure ). A current of 2.90 A is suddenly started in the coil.
angular acceleration = torgue / moment of inertia
The Attempt at a Solution
Here is the image...
It rotates around axis 2
I can't figure out how to find the moment of inertia of this shape. I know the basic formula, of moment of inertia and how you find it, but can't figure out how to tell how the mass is distributed. I'm pretty sure the parts of the rectangle that are parallel to the axis of rotation can be excluded, because they will cancel each other out, but the bars on the side are confusing me.
Any help is greatly appreciated.
