A piece of composite-lumber flooring is a = 77 mm wide. It consists of a layer of medium-density fiberboard [E = 4.3 GPa] that is b = 11 mm thick and a layer of bamboo [E = 35 GPa] that is c = 7 mm thick. Determine the distance to the centroid of the transformed section from the bottom of the board.
