"When the load is uniformly distributed on a beam of any cross-section, it will sustain a load twice as great as when the load is applied in the middle between the supports." — Hallock, 1905

"Then went Samson down, and his father and his mother, to Timnah, and came to the vineyards of Timnah: and, behold, a young lion roared against him. And the Spirit of Jehovah came mightily upon him, and he rent him as he would have rent a kid; and he had nothing in his hand: but he told not his father or his mother what he had done." Judges 14:5-6 ASV <p>Illustration of Samson tearing apart the jaw of a lion he is killing. He is wearing a tunic and cloak. He has long hair and a thick beard. The lion appears to be alive still. The terrain is rocky with some foliage.

"Since the strength of the fibers in adhesion is very much less than in tension and compression, adhesion enters into nearly every test as an important factor. Thus, if a piece of wood consisting of several fibers is tested in tension, the fibers a and b would probably not break at all, but be merely pulled out, the failure, as far as they are concerned, being due to lack of adhesion and not to a lack of tensile strength. Every tension test presents numerous cases of this king, the broken fibers presenting no even fracture, but being splintered and drawn out especially if the wood is good."&mdash;Government Printing Office, 1897
