A uniform brick of length L is laid on a smooth horizontal surface. Other equal bricks are now piled on as shown, so that the sides form continuous planes, but the ends are offset at each brick by a distance L/a, where a is an integer. How many bricks n can be used in this manner before the pile topples over?
