How much weight can a 2" x 6" wood plank support ...
Aug 19, 2008· There is a 2" x 6" wood plank attached horizontally to two vertical 4" x 4" posts. The posts are spaced 3 feet apart. The plank is attached to each post with 2 bolts/nuts on each post. The plank is located 8 feet high on the posts from the ground. The plank extends four feet from the 2nd post. So the plank is a total of 7 feet long. The posts are anchored in the ground with concrete.

Breaking (martial arts) Wikipedia
This feat was demonstrated in China in the early part of the last century, by wellknown qigong masters, many who performed it with 5 or 7 bricks or slabs of concrete, and the really talented masters could break two bricks, even if unconnected to one another ( breaking the third and sixth bricks in a stack of 7).
Shattering Science and Glass Physics PhysicsCentral
Shattering Safely. Stronger glass addresses one aspect of the glass safety issue, but all glass is destructible. Inevitably, even very strong glass will break under too much force, and this breaking can release huge amounts of energy capable of causing serious damage and injury.
Uniaxial Tension and Compression Testing of Materials
Young's modulus with that yield strain as the xintercept, and locating the point where this line intersected the stressstrain curve. The values for yield stress and yield strain were used along with Eqn. 5 to calculate values for U el max, the material's maximum capacity to elastically absorb energy.
