The concept of a muzzle brake was first introduced for artillery. It was a common feature on many anti-tank guns, especially those mounted on tanks, in order to reduce the area needed to take up the strokes of recoil and kickback. They have been used in various forms for rifles and pistols to help control recoil and the rising of the barrel ...
Crack tip opening displacement (CTOD) or is the distance between the opposite faces of a crack tip at the 90° intercept position. The position behind the crack tip at which the distance is measured is arbitrary but commonly used is the point where two 45° lines, starting at the crack tip, intersect the crack faces. [ 1 ]

The built up edge effectively changes tool geometry and rake steepness. It also reduces the contact area between the chip and the cutting tool, [1] leading to: A reduction in the power demand of the cutting operation. [1] Slight increase in tool life, since the cutting is partly being done by the built up edge rather than the tool itself. [4]
A tip-up is a device used while ice fishing to suspend live or frozen bait at a set depth through a hole drilled in the ice with an auger, and detect when a fish strikes, without having to be in contact with this piece of gear.
