scene 4 of 9
Diagram shows an “I” bar consisting of three sections, 1, 2 and 3. The section 1 on top is horizontal with a length of 3.0 inches and thickness 0.5 inches. The section 2 is vertical and has a height of 6.5 inches and thickness 0.5 inches. The section 3 is horizontal and has a length of 6.0 inches and thickness 1.0 inches. The centroid is at the origin of the x y axes on the vertical section 2 close to the bottom.

Before continuing, the centroid location and the area moment of inertia of the flanged shape about the centroidal axis must be computed.
