A composite solid consists of a rectangular block of lightweight concrete and a
triangular wedge of steel with dimensions as shown. The rectangular block has a
2 ft radius circular hole drilled through its full depth, perpendicular to the front
and back faces.
Assume densities yc = 125 lb/ft³, and ys = 493 lb/ft³.
