Jambatan baru 6 bulan guna beralun macam riben menari-nari :D (video)

disebabkan frequency molekul2 material jambatan bergerak then dh jd getah no... dasat gak fenomena nih...adakah ini boleh terjadi dkt bngunan tinggi2 spt KLCC? cuba bayangkan KLCC dance mcm tu...ala2 gerudi inul....

   member aku keje jurutera cakap klcc jugak bergoyang!beralun gitu tapi kite x sedar.

JohnDeSouza

engineer depa sengaja wat jambtan tu beralun kot utk atasi masalah resonan

mycos79

jambatan penang ader beralun mcm tuh ka?
mana tau memang dia design utk elak gegaran...

discussion in this thread does ring a lot of bells....amygdala hjiack ni actually....

hehehehehhe ya allah....good thread

he he... coba naik motor atas jambatan tu... bleh rasa angin lintang menolak motor... seriau worrr..

rasanya daya damped jambatan tu lagi tinggi dari daya angin tu.. tu yang jambatan tak bergoyang tu...

JohnDeSouza

time petang rasanya ada angin lintang.

    hoho! mau jd fobia kalau aku keja kat seberang sana sebab duk terbayang jambatan dlm video ni...hehe...
dalam video last tu, ade sorang prof berjalan atas jambatan tu...relek je...

vibrating bridge

oh nooooooooooooooo resonance ke aiiiiiiiiii bahaya ni jadi macam satu bridge kat States tu kan yg collapsed sebab depa lupa factor resonance mbhcsf Post at 22-5-2010 14:11

    tadi tak faham komen mbhcsf nih.... skrg baru paham apa tu resonance....
maksud mbhcsf bridge ni lah kan? :

U.S Tacoma Narrows Bridge

Korang agak la....
kalau jambatan MRR kena camni, jadi camne kan?

JohnDeSouza

jambatan penang x ada alun2 camni.ujan ka ribut ka dia tetap gagah.cuma kalau bawak reta jgn la laju sgt.

    Yes, aku tau pasal benda ni pun hasil menonton NatGeo pasal Tacoma Bridge nih..

Konsep resonance ni jugaklah kalau aku tak silap la, diaplikasikan dlm trick nak pecahkan gelas oleh penyanyi soprano...betoi ka?

let me briefly explain the phenomena
Jambatan bergoyang disebabkan "resonance frequency"

Angin: ...

tq dgn info ni.
maksudnya lama2 ia runtuh psl struktur2 binaan die da "hancur/mix" ms beralun tu ke?

aku mcm faham kenapa tak retak masa bralun2 tu.
sbb tekanan/daya yang bertukar2 spjg jambatan ms beralun tu mengelakkan jalan tu dr retak terus.

betul ke kefahaman xde tauliah aku neh. hehe maklumlah blaja fizik smpi form5 je

    beria aku cari makna natgeo kat pakcik gogel...rupanya national geographic...keh3...apo la aku ni yg ni pun xtau...
kena cari gak ni natgeo pasal ni...mesti best...

xtau lak pulak pasal soprano-resonance-gelas pecah tu...

aku pun ala2 faham mcm ko jgk...haha! maklum la kan kiter blja fizik takat form 5 pahtu result cam ampes jerr...
bila tgk kejadian camni mula la mulut melongo...rasa macam magik baekkk punya...

rose_liz

bukan aku je amazed ngan kejadian ni...org2 kat rusia pun heran...tapi kalau ikut kenyataan berikut, mmg patut la...kita kurang terdedah dgn menda2 yg jadi jarang2 nih...macam tsunami la...bila dah jadi je, macam2 info baru didedahkan kpd public.


Resonance is a common thread which runs through almost every branch of physics, and yet a lot of people have never studied it. Without resonance we wouldn't have radio, television, music, or swings on playgrounds, not to mention cool gismos like Tesla coils. Of course, resonance also has its dark side. It occasionally causes a bridge to collapse, a helicopter to fly apart, or other inconveniences. Unlike black holes, time travel, and quantum mechanics, resonance is common place and easy to observe. Yet, it is one of the most striking and unexpected phenomenon in all of physics.

tak bergoyang pun dah retak...
kalau dah macam dalam youtube tu paham sendiri ler
