Which is more likely to break—a hammock stretched tightly between a pair of trees or one that sags more when you sit on it?
ANSWER: The hammock which gets stretched more when you sit on it has more elastic properties. The other one which is tied very tightly between two trees, will break first. Because before breaking, everything goes to it’s maximum stretched position. As the breaking strain is the parameter on which all these things depend on, the hammock which gets stretched more after someone sits on it, has more elastic properties than the other, it will break later.
