Three identical uniform bricks of mass m and length l are stacked on top of each other. (a) what is the maximum distance d so that the stack does not tumble over? (hint: consider the top two bricks first, then add the bottom brick) (b) what is the maximum distance d that can be achieved by optimal stacking of an infinite number of bricks?
