Second Moments of Area- Exercise 3

A beam has the cross-sectional shape shown below. The wall thickness is constant at 0.25 in. Determine its

  1. Centroidal coordinates (,) relative to the reference axes shown,
  2. Moments of inertia about the centroidal x and y axes, Ixc and Iyc
  3. Polar moment of inertia about the centroidal z axis, Jc
  4. Product of inertia with respect to centroidal x and y axes, Ixcyc.

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.
