1. The problem statement, all variables and given/known data A homogenous brick with length L, is on a horizontal surface. On this brick are put one after another other bricks, which are the same with the first. Every brick is moved along L/5 units horizontally from the predecessor one. How many bricks can be put without disordering the equilibrium? 2. Relevant equations (L/2)/(L/5)=2.5 3. The attempt at a solution Since the bricks are homogeneous then the center of gravity is in the middle. So in the point L/2. So (L/2)/(L/5)=2.5, so there are 2 bricks.
