Question:

Determine the location of the centroid y' of the beam constructed from the two channels and the cover plate. If each channel has a cross-sectional area Ac and a moment of inertia about a horizontal axis passing through its own centroid Cc, of Ix'c , determine the moment of inertia of the beam’s cross-sectional area about the x' axis.

Given:

a = 18 in

b = 1.5 in

c = 20 in

d = 10 in

Ac = 11.8 in2

Ix'c = 349 in4
