Springboard

The Maxiflex Model B, the board used in all major competitive diving events,[1] is made out of such aluminum, and is heat treated for a yield strength of 340,000 kPa (49,000 psi).

Since the resulting system is in an approximately linear regime, it may be modeled fairly accurately by a second order differential equation.

[3] The fulcrum on competitive diving boards travels over a range of 0.61 metres (24 inches),[4] and is set by way of a foot wheel that is approximately 0.35 m (14 in) in diameter.

American artist Norman Rockwell's painting titled Boy on High Dive (1947) shows a boy (Rockwel's youngest son, Peter) peering over a typical wooden springboard of the early 20th century era at the 20 feet height.

In the incident, 14-year-old Shawn Meneely made a "suicide dive" (holding his hands at his sides, so that his head hit the bottom first) in a private swimming pool and was seriously injured and became a tetraplegic.

It filed twice for Chapter 11 bankruptcy protection and was successfully reorganized into a new swimming pool industry association.
