Ok, I failed high school physics.?
Let's say we have a rod made of oak 2" thick and 16' long. Imagine a weight heavy enough, when placed in the center, to make the rod sag and then break. Now let's put the rod in a support so that only 3" of the rod is protruding. Hang the same weight from that, and the rod doesn't break. Why not? What principle is at work here?
