Bungee jumping (or bungy jumping) is the sport of jumping from a tall structure while connected to a large rubber band. The tall structure is usually a fixed object, such as a building, bridge, or crane; but it is also possible to jump from a movable object, such as a hot-air-balloon or a helicopter, that has the ability to hover over one spot on the ground; fixed-wing aircraft are clearly unsuitable because they only stay aloft when moving rapidly forward. The intense thrill comes as much from the free-falls base jumping as from the rebounds.
When the person jumps, the cord stretches to absorb the energy of the fall, then the jumper flies upwards again as the cord snaps back. The jumper oscillates up and down until all the energy is dissipated.
The word bungee (pronounced bunjie) first published around 1930 and was the name for rubber erasers. The word bungy, as used by A J Hackett, is Kiwi jargon for flexible handle. Cloth-covered rubber cords with hooks at the ends were present for decades under the generic name spring element cords.
In the fifties David Attenborough had gotten and in a BBC film crew back from Pentecost island in Vanuatu, young men, who jumped from the high wooden platforms with the vines to overall length of the land divers, which were bound to their Knchel as test of the courage. This film spurred Chris bakers of Bristol, England, to use flexible rope in a kind urban vine jumping. The first modern spring element jump was formed on 1 April 1979 of the 250ft Clifton the abolition bridge in Bristol and formed by four members of the dangerous Sport-Vereins. More berbrcker, led of David Kirke, briefly after were held, but continued with jumps spreading in US of golden the gate and royal of the ravine bridges, (this last jump past promoted and transferred on the American program in the television, which is unbelievable), the concept world-wide. By 1982 they jumped from the mobile cranes and from the hot-air balloons and sat down on commercial announcements.
One of the first operators of a jumping interest of the commercial spring element, making possible for the public, was these jumps of the faith to experienced, new Zealander, a J Hackett, which formed its first jump of the bridge Greenhithe Aucklands 1986. During the following years Hackett accomplished a number of jumps of the bridges and by other structures (including Eiffel essay) and established general interest in the sport. Hackett remains one of the largest commercial operators, with interests in some countries. The world first commercial spring element place of assembly was the Kawarau bridge Bungy with Queenstown in the south island of New Zealand.
Despite the associated danger of jumping a large height, some million successful jumps took place since 1980. This is spring element operators radical in agreement with the standards and guidelines zuzuschreibend, the jumps, as regulate doubling controlling of computations and of attachments for each jump. As with each possible sport, injuries can occur calmly (down to see), but it few calamities gave. A relatively general error in the cases of calamity is to use a too long cord. The cord should be essentially shorter as the height of the jumping platform to permit it area to expand. If the cord achieves its natural length, those more berbrcker either begins to slow down or, hold to accelerate. Slopes after the speed of the waste. Can possibly not even begin slow down, until the cord already expanded a little, because the resistance of the cord is for distortion at the natural length zero, and only after and some time gradually increases lasted to even correspond to the weight berbrckers. Possible energy for a discussion over the spring, which is constant and which Kraft also see, which are required, in order spring element cords and – other Frhling-wie of articles to distort.
