Problem 3.18 || Forces & Moments in Slender Members | Mechanics of Solids | Crandall, Dahl, Lardner

A section of a scaffold consists of a plank laid across two supports and extending a distance a on either side of the supports. A mason working at the center of the plank thinks that he should stack his supply of bricks on the ends of the plank in order to minimize the bending moment in the plank. Is he correct? If equal numbers of bricks are stacked at each end of the plank, for what weight of bricks, WB, is the maximum bending moment in the plank a minimum? The man weighs WM.
