1. The problem statement, all variables and given/known data Your task in a science contest is to stack four identical uniform bricks, each of length L, so that the top brick is as far to the right as possible without the stack falling over. Is it possible, as the figure shows, to stack the bricks such that no part of the top brick is over the table? 2. Relevant equations Torque=rFt 3. The attempt at a solution I think this is a torque question. However, since it is a stack of blocks I can't figure how to go about summing up the torques. Any hints would be greatly appreciated.
