If you put a uniform block at the edge of a table, as shown at
left part of (Figure 1), the center of the block must be over the
table for the block not to fall off.
If you stack two identical blocks at the table edge, as shown at the right part (Figure 1), the center of the top block must be over the bottom block.
and the center of gravity of the two blocks together must be over the table. What is the maximum overhang possible?
