Semalam aku tengok berita Buletin Utama,tiba2 ada berita mengenai jambatan tu teralun menari2.Rupanya fenomena ini berlaku di Russia iaitu jambatan yg baru 6 bulan dah terjadi mcm tu.
Kenapa ya?Apa pun mari tgk video ini..
May 21, 2010 — A 7km (four miles) long bridge over the Volga river in Volgograd, Russia, has been shut after the structure started to wobble. Strong currents in the river caused by the flow of water from melting snow upstream apparently loosened one of the bridge’s vertical supports. Officials are deciding whether to reopen the bridge.
rupanya sebab arus kuat dari sungai tu yang menyebabkan fenomena ni terjadi. kejadian seperti ni pernah terjadi kat U.S Tacoma Narrows Bridge pada tahun 1940, jambatan tu roboh selepas 4 bulan disebabkan windstorm (video bawah).
