The question states, using mohrs cirlce, determine for the area indicated the values and orientation of the principal centroidal axis. So far I have this: i feel like only the Ixybar value is correct. i'm stuck on how to calculate the Ix and Iy for the two triangles and whether the values i have for those are correct or not. and from there, how do I go about getting the circle, and getting the theta and everything else i need. can someone please help!
