Hoof nippers allow you to trim around the hoof wall until the horse's foot is the proper length. Every barn or stable should be equipped with at least one of these essential horseshoeing tools.
Asked by: Anthony Matarazzo. Mach number is a common 'ratio' unit of speed when one is talking about aircrafts. By definition, Mach number is a ratio of the speed of a body (aircraft) to the speed of sound in the undisturbed medium through which the body is traveling.
Cruise is at 0.78 to 0.79 mach depending on the fuel consumption rate. Mach is the speed of sound and varies by altitude, temperature and air density. At 35,000 feet altitude, mach 1 is 663.5 mph for standard conditions. It is a few mph faster for lower altitudes and a few mph slower for higher altitudes. For standard conditions in the 33,000 to 39,000 typical cruise altitude, 0.78 to 0.79 mach would be 515 to 525 mph.
