A blunt body fired from a gun against a supersonic flow in a wind tunnel, producing a bow shock. A bow shock, also called a detached shock or bowed normal shock, is a curved propagating disturbance wave characterized by an abrupt, nearly discontinuous, change in pressure, temperature, and density.
Bowing the body of a string instrument (which can include bowing the sound box, neck, tuning pegs, or scroll) produces a quiet sound whose amplitude differs according to the place bowed, bow pressure and bow speed. At most the sound is a whisper of the bow hair moving over the wood.
In astrophysics, bow shocks are shock waves in regions where the conditions of density and pressure change dramatically due to blowing stellar wind. [1] Bow shock occurs when the magnetosphere of an astrophysical object interacts with the nearby flowing ambient plasma such as the solar wind .
Taiwan President Tsai Ing-wen said on Monday the self-ruled island would not bow to pressure after her high-profile trip to Latin America, including stops in the United States, which drew ...
Two ways in which the martelé bowstroke is commonly notated. An excerpt from Dotzauer's cello étude no. 6, played with martelé bowing. Martelé (French pronunciation: [maʁt(ə)le]; literally meaning "hammered") [1] [2] is a percussive bow stroke used when playing bowed string instruments, though the Italian martellando and martellato are also applied to piano and vocal technique, and even ...
The effect that pressure distribution has on a surface is known as the form effect. [6] A sharp bow on a conventional hull form would produce waves and low drag like a bulbous bow, but waves coming from the side would strike it harder. The blunt bulbous bow also produces higher pressure in a large region in front, making the bow wave start ...
The deep-sea water pressure that appears to have crushed the 22-foot craft would have been roughly equivalent in ... and was found on the seabed around 1,600 feet from the Titanic’s bow, ...
Increasing pressure on the strings is the primary way to produce louder notes on the violin. Pressure is added mainly by the index finger of the bowing hand. Another method sometimes used to increase volume is using greater bow speed; however, a violinist can increase bow speed and still play softly at the same time.
