Part 1: You have an unlimited supply of indestructible bricks that are 10cm long and 4cm high. After some thougt, you realize that building a huge wall to keep immigrants out is a dumb idea, you decide to do something more creative with them. Since sticking things together, reinforcing structures and using concrete are all techniques foreign to you, you decide to put one brick on the ground, put another one on top of if, then another one on top of that, etc. How far to the right can you get the edge of the last brick from the center of the first one without making the whole structure colapse? Part 2 You now decide to make a sort of an arc. You start stacking bricks leaning towards the right, and then you stop and start stacking them towards the left, until the center of the last brick is over the center of the first brick. If you draw a line from the bottom brick to the top brick in this structure, what can the maximum distance of a brick from that line be?
