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.
A Machmeter gives us that information. Since Mach is a critical number, we fly at a percentage mach, rather than an airspeed, (typically about 0.85 mach or 85% of the speed of sound) any time that we are likely to get near supersonic. Hope that helps
