As spring approaches, many people put up birdfeeders for wild birds. Inorder to keep squirrels away, the feed?

feeders are often suspended from
wires. Suppose a feeder is suspended by wire to two trees standing a
distance D apart and attached at a common height above the ground. The
feeder hangs midway between the trees, but at a distance d below the
height at which the wires are attached to the trees. There are three
configurations to consider whose shapes resemble the letters T, V, and
Y. What configuration will minimize the total length of wire needed?

It doesn’t matter. The squirrels will get to it anyway. Some people have success by mounting plastic soda bottles on the wire in a way that allows them to spin freely when a squirrel steps on them. In addition, the feeder needs to be high enough off the ground that a squirrel can’t jump ut to it.
