In mechanics and physics, Hooke's law of elasticity is an approximation that states that the extension of a spring is in direct proportion with the load applied to it. Many materials obey this law as long as the load does not exceed the material's elastic limit. Materials for which Hooke's law is a useful approximation are known as linear-elastic or "Hookean" materials. Hooke's law in simple terms says that strain is directly proportional to stress.
Mathematically, Hooke's law states that
where
When this holds, the behavior is said to be linear. If shown on a graph, the line should show a direct variation. There is a negative sign on the right hand side of the equation because the restoring force always acts in the opposite direction of the displacement (for example, when a spring is stretched to the left, it pulls back to the right).
Hooke's law is named after the 17th century British physicist Robert Hooke. He first stated this law in 1660 as a Latin anagram, whose solution he published in 1678 as Ut tensio, sic vis, meaning, "As the extension, so the force".
Chapter 14 is an American alternative metalcore rock band from Carlsbad, California currently consisting of vocalist Chad Ackerman (Destroy the Runner, As I Lay Dying, Austrian Death Machine), guitarist Tanner Sparks (Destroy the Runner), bassist Edwin Peraza, and Jonathan Knauer on drums.
Founded in 2003 by Ackerman and Sparks the band also consisted of drummer Mike Catalano (Chiodos, Destroy the Runner), guitarist Noah Slifka (In Fear and Faith) and bassist Eddie Hudson (Paper Mache). The band was unable to put together a full-length album but did complete two full U.S. tours and several demos without a label or financial backing.
After four years trying to land a record deal the band split up in 2007 when Ackerman and Sparks were offered the roles of vocalist and bassist for Destroy the Runner’s departing Kyle Setter and Jeremiah Crespo respectively. Noah Slifka went on to join In Fear and Faith the same year while Mike Catalano would join back up with Ackerman and Sparks in Destroy the Runner in 2008. Eddie Hudson moved on to play bass for the band Paper Mache. Chad explains what happened with Destroy The Runner and what Chapter 14 has for future plans
