Mach Number
Mach number (M or Ma) (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Moravian physicist and philosopher Ernst Mach. : \mathrm = \frac, where: : is the local Mach number, : is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and : is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number. The local spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supersonic Speed
Supersonic speed is the speed of an object that exceeds the speed of sound ( Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately . Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MACH-4 (Marvel Comics)
Abner Ronald Jenkins, also known as the Beetle, MACH-1, MACH-2, MACH-3, MACH-IV, MACH-V, MACH-VII and MACH-X, is a fictional character appearing in American comic books published by Marvel Comics. Created by writer Stan Lee and artist Carl Burgos, he debuted in ''Strange Tales'' #123 (August 1964) as the original Beetle, a supervillain wearing an armor plated, mechanical suit he had designed himself after growing frustrated with his ordinary job as an aircraft mechanic and deciding to turn to crime. Although in his first appearance he fought the Human Torch and the Thing of the Fantastic Four, later storylines established Jenkins as a recurring foe of Spider-Man, usually working as a henchman for various criminal organization opposing the hero. Jenkins later formed his own criminal organization known as the Sinister Syndicate. After abandoning his Beetle persona, Jenkins was recruited into the Thunderbolts—a supervillain team assembled by Helmut Zemo to pose as heroes in orde ...

Fly Castelluccio Mach
The Fly Castelluccio Mach is a family of Italian paramotors that was designed and produced by Fly Castelluccio of Ascoli Piceno for powered paragliding. Now out of production, when it was available the aircraft were supplied complete and ready-to-fly.Bertrand, Noel; Rene Coulon; et al: ''World Directory of Leisure Aviation 2003-04'', page 67. Pagefast Ltd, Lancaster UK, 2003. ISSN 1368-485X Design and development The Mach was designed to comply with the US FAR 103 Ultralight Vehicles rules as well as European regulations. It features a paraglider-style wing, single-place accommodation and a single Solo 210 engine in pusher configuration powering a two-bladed or four-bladed wooden propeller through a reduction drive. As is the case with all paramotors, take-off and landing is accomplished by foot. Inflight steering is accomplished via handles that actuate the canopy brakes, creating roll and yaw. Variants ;Mach 1 Light :Model with a Solo 210 engine in pusher configuration ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kawasaki H2 Mach IV
The Kawasaki H2 Mach IV was a 750 cc Straight-three engine, 3-cylinder Two-stroke engine, two-stroke production motorcycle manufactured by Kawasaki motorcycles, Kawasaki. The H2 was a Kawasaki triple sold from September 1971 through 1975. A standard, factory produced H2 was able to travel a quarter mile from a standing start in 12.0 seconds. It handled better than the Mach III that preceded it. By the standards of its time, its handling was sufficient to make it the production bike to beat on the race track. Nonetheless, its tendency to pull wheelies and a less than solid feel through high speed corners led to adjustments to the design as it evolved. More than any other model, it created Kawasaki's reputation for building what motorcycle journalist Alastair Walker called, "scarily fast, good-looking, no holds barred motorcycles", and led to a further decline in the market place of the British motorcycle industry. History In September 1971 the H2 was a direct result of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dark Triad Dirty Dozen
The Dark Triad Dirty Dozen (DTDD) is a brief 12-question personality inventory test to assesses the possible presence of three co-morbid socially maladaptive, dark triad traits: Machiavellianism, narcissism, and psychopathy. The DTDD was developed to identify the dark triad traits among subclinical adult populations. It is a screening test. High scores on the DTDD do not necessary correlate with clinical diagnoses. Validity Jonason and Webster conducted several validity tests of the DTDD as part of its development. Relevant outcomes have all shown statistically significance weaknesses. * Convergent validity (i.e. the extent to which two tests that measure the same construct are strongly related) was assessed by comparing the DTDD subscales (i.e. Machiavellianism, psychopathy, narcissism) with established measures of each subscales; Mach IV, SRP-III, and NPI respectively. DTDD Machiavellianism was correlated with Mach IV at 0.34, DTDD psychopathy with SRP-III at 0.42 and DTDD Na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
