A horizontal rod of length 508 cm is held aloft by friction
against a brick wall on one end and on the other end by a rope of
length 628cm, which itself is attached to the brick wall directly
above where the rod touches the wall. The coefficient of static
friction between the wall and the rod is 0.435. A ball of the same
weight as the rod hangs from the rod.
What is the minimum distance ball must hang from the wall in order
to the rod to stay stable?
