1. The problem statement, all variables and given/known data Consider two identical bricks, each of dimensions 20.0 cm x 10.0 cm x 6.0 cm. One is stacked on the other, and the combination is then placed so that they project over the edge of a table. What is the maximum distance that the top brick can extend beyond the table edge without tipping? 2. Relevant equations I don't really know... 3. The attempt at a solution I would say at 10 cm, because that's where the center of gravity is. But it sounds too simple to be true... =/ Thanks!
