A piece of composite-lumber flooring is a = 75 mm wide. It consists of a layer of medium-density fiberboard [E = 3.2 GPa] that is b = 20 mm thick and a layer of bamboo [E = 37 GPa] that is c = 4 mm thick. Determine the distance to the centroid of the transformed section from the bottom of the board.
