The committee's report was printed in 1888 and recommended a drop energy of 1,260 foot-pounds force (1,710 J). In April 1892, the Home Office revised this based on an energy of 840 foot-pounds force (1,140 J). In practice, however, the hangmen ignored this table and used considerably longer drops.
Tribology is the science and engineering of understanding friction, lubrication and wear phenomena for interacting surfaces in relative motion.It is highly interdisciplinary, drawing on many academic fields, including physics, chemistry, materials science, mathematics, biology and engineering. [1]
The history of the Ballistic Research Laboratory dates back to World War I with the Office of the Chief of Ordnance (OCO) within the U.S. Army.

The weight of an object on Earth's surface is the downwards force on that object, given by Newton's second law of motion, or F = m a (force = mass × acceleration). Gravitational acceleration contributes to the total gravity acceleration, but other factors, such as the rotation of Earth, also contribute, and, therefore, affect the weight of the ...
If this was just five years ago, let alone 10 or 20, the prospect of 72-year-old Bill Belichick as a college football coach would have been more about a splashy hire than the promise of great success.
