Quarter buckle - This is a rare defect where the fibers are elongated in the quarter regions (the portion of the strip between the center and the edge). This is normally attributed to using excessive roll bending force since the bending force may not compensate for the roll deflection across the entire length of the roll.
The average value of the force adaptors trimmed the value of k 0 for the actual grade being rolled. Also the slope of the force adaptors corrected the work hardening rate, k 3 for the same grade of steel. The value of k 3 for super-strapping was approximately twice that for normal tin-plate. This made switching between grades from coil-to-coil ...
A small holding force exerted on one side can carry a much larger loading force on the other side; this is the principle by which a capstan-type device operates. A holding capstan is a ratchet device that can turn only in one direction; once a load is pulled into place in that direction, it can be held with a much smaller force.
In chess, a relative value (or point value) is a standard value conventionally assigned to each piece. Piece valuations have no role in the rules of chess but are useful as an aid to evaluating a position. The best-known system assigns 1 point to a pawn, 3 points to a knight or bishop, 5 points to a rook and 9 points to a queen. Valuation ...

Fig. 1: Critical stress vs slenderness ratio for steel, for E = 200 GPa, yield strength = 240 MPa.. Euler's critical load or Euler's buckling load is the compressive load at which a slender column will suddenly bend or buckle.
Rare Washington quarters minted in 1932 can sell for as much as $13,573, according to USA Coin Book. Errors and rare mintages give coins the highest re-sale value, per The U.S. Sun.
The Mint produced and shipped a total of 34.3 billion quarters during the program, with the average annual mintage reaching 3.5 billion quarters. At least 400 million of each quarter was minted.
