A piece of composite-lumber flooring is a = 85 mm wide. It consists of a layer of medium-density fiberboard [E = 5.0 GPa] that is b = 12 mm thick and a layer of bamboo [E = 25 GPa] that is c = 7 mm thick. Determine the distance to the centroid of the transformed section from the bottom of the board.

Two toy blocks are stacked to form an L-shape. Each block has dimensions a = 23.3 mm and b = 69.9 mm. Determine the vertical distance from the table to the centroid of the shape.
