Consider an ideal (ie. cannot stretch, and can bend freely) cable
suspended from two points of equal height (that are closer together
than the cable's length). The cable adopts the shape of a catenary
(hyperbolic cosine).
Now suppose you hang a weight from the center of the cable. Does the
cable's center of mass move up, down, or remain at the same height?
From the same readings, here's another (much easier) nifty question.Suppose instead of pulling downward on the center of the cable, I
