Second Moments of Area- Exercise 4

The cross-sectional shape of a machined section with constant wall thickness is shown below. Determine its

  1. Centroidal coordinates (,) relative to the reference xy axes,
  2. Moments of inertia about the centroidal x and y axes, Ixc and Iyc
  3. Moments of inertia about the reference x and y axes, Ix and Iy
  4. Product of inertia about the centroidal x and y axes, Ixcyc
  5. Orientation angle of the x principal axis, qp
  6. Principal moments of inertia, Ixp and Iyp.

Round up your answers to three decimal places. You can submit one answer at a time by leaving the remaining answer fields blank or you can submit all answers together.
