Is there any specific reason for rounding off intermediate values during the analysis stage?

[@Engineer4Free]

No. Just did it to save time in the video but that is sloppy, you should maintain as many decimal places as possible until the end.

[@l3igl2eaper]

@@Engineer4Free Roger that. Thanks for the awesome content!

I believe that the moment of inertia via the FE reference book version 10.0 (Statics section) should be: I_x=I_xc + ((d)^2 * A) Where I_xc=(b*h^3)/12 you had the I_xc=(b*h^3)/3 which is incorrect. Can you please advise?

[@Chan-ux7ej]

The 1/12 is correct if you rotate a rectangular shape about its centroid. The 1/3 component used for this problem is correct, as the rotation not about the centroid, but its edge. The parallel axis theorem can prove this.
