whoops you walk [(pi)(delta)]/[360*R*sin((delta)/2)] times as far… missed the radius on the first one. Where R is the radius of the curve and delta is the angle of the curve… assuming the person that designed this made is a true curve.
Oops, 𝜋 times would give you the full circumference, but you have to walk only half of that, 𝜋/2. Therefore you only have to walk (𝜋/2-1)*100 = 57% more steps.
Just like with any movable bridge – sound alarms, close both ends from entering traffic, wait for the people on the bridge to leave, raise. And if you do this before the ship comes along, it doesn’t have to wait for a minute.
The bridge takes 4.5 minutes to rotate and is 105 meters “long”.
In a worst case scenario someone just entered the bridge and needs one minute to the other end in normal walking speed, two if he is old or disabled, three if he’s deaf and blind and four if he’s drunk or injured and someone has to take him away. That’s about 6.5 – 10.5 minutes in total.
Not a big problem, but a normal draw bridge for pedestrians only has a small gap of 10 – 20 meters (See the small corridor in the picture where actually all the ships cross?), so no one should need longer than 20 seconds from one end of the opening bit to the other and it opens in maybe a minute, so it’s about five times faster. This bridge is cool, but not that cool to be that useless.
A really cool bridge would have the shape of an rotating plain “O” with one half under water iwhen it moves in vertical position and ships driving right through it.
:O That’s my hometown bridge! How dare you put it on Failblog! Lmaoo!! Although you do have to walk a mile to get over it…. If you’ve ever seen the bridge go up, especially at night, it’s quite a beautiful sight
“The bridge takes as little as 4.5 minutes to rotate through the full 40° from closed to open, depending on wind speed.” – wiki. No mention of time-to-clear, but it’s only 105 m (344 ft) so probably not more than 5 minutes or so.
You mean to tell me they took the time to construct a moving bridge rather than build… say… a bridge as high as the minimally lifted bridge with some *gasp* stairs?!?! Cause god forbid people actually walk up some stairs.
Well, considering it’s quite a ‘cultured’ city, I suppose it makes sense. Also, I think adding an extra bridge that did the exact same thing as the other nine would get a bit boring. :>
It works. How is it not proper if it works? That, and it’s simple. Counter balance system. How is a simple, effective, efficient bridge not proper? How much energy does it take for a bridge to split in the middle and open up? How much energy does it take for this bridge to flip up? I guess you could say the money for proper infrastructure gets wasted on all this extra energy expenditure?
newcastle a cultured city take it from a girl who lives there there is nothing cultural about newcastle.
things newcastle is famous for:
geordie. which is a acent
newcastle brown ale which has the most aritfical presevertives and flavourings then any other ale in the uk.
and drunken late night kebabs after a fight in a club lol .
dont belive me look for geordie shore online.
Look up the Sage Gateshead and the Baltic contemporary art museum. Both those rather beautiful buildings are right next to that bridge. The idea you suggested would look ridiculously out of place and compared the the other bridges on the Tyne would spoil the look and feel of Newcastle’s quayside.
Not to mention accessibility problems and the affects of weather…
Have a look at the bottom picture and, using the people as scale, look at how high the very middle of the bridge is to allow mast clearance. Now, how steep are you planning on these stairs to be? Or are you planning on knocking some buildings down so they can start 300 yards from the waters edge?
I hadn’t seen it before either. It’s the Gateshead Millennium Bridge, linking “Gateshead’s Quays arts quarter on the south bank, and the Quayside of Newcastle upon Tyne on the north bank” (per Wikipedia), but that still doesn’t mean anything to me (except it’s somewhere in England); however further research shows that Gateshead and Newcastle upon Tyne are communities in the northeast part of England, not far from the coast. Again quoting Wikipedia, “Gateshead town centre and Newcastle City Centre are joined by seven different bridges across the Tyne, including the landmark Gateshead Millennium Bridge.” So, it’s a landmark I’d never seen before.
It’s a clever design, but I fail to see any advantage over the more conventional ways to raise a bridge. Seems like a gimmick, though a very ingenious one. It does lengthen the travel, and by tilting the roadway, would cause anything on the roadway (like trash or loose paving) to fall into the river. However I also agree that stairs are not a valid option, even though this is a pedestrian-only bridge; it wouldn’t be handicapped-accessible (unless there was an elevator at each end) and since it’s intended for pedestrians AND cyclists, you’d have cyclists carrying their bicycles on the stairs, which is hardly ideal for them OR the pedestrians. A spiral ramp would be interesting but expensive and would GREATLY increase the travel distance (since a ramp goes 12 horizontal for every one vertical).
Wow how nice –thought it was a photoshop at first! Also love all the math geek comments at the beginning. Nice to see art trumping utility occasionally. Thats why we started painting those cave walls in the first place.
Ah, I miss Newcastle…lovely city.
in case anyone else wondered where this was…

Looks cool except you end up walking [(pi)(delta)]/[360*sin((delta)/2)] times as far as a straight bridge.
whoops you walk [(pi)(delta)]/[360*R*sin((delta)/2)] times as far… missed the radius on the first one. Where R is the radius of the curve and delta is the angle of the curve… assuming the person that designed this made is a true curve.
Of course the person that designed this made is a true curve.
Technically, all curves are “true” curves (but are they all real? math nerd joke inside), but they may not be circular arcs.
Oh no! Not more exercise!
wtf is this eq.? considering the bridge is exactly half of a circumference, its distance is 𝜋 times the distance of a straight bridge.
214% more steps to cross it.
but it is nice to think what happens in your eq. when 𝛿 goes to zero.
Oops, 𝜋 times would give you the full circumference, but you have to walk only half of that, 𝜋/2. Therefore you only have to walk (𝜋/2-1)*100 = 57% more steps.
It is not 1/2 a circumference; nowhere near: http://g.co/maps/y4axr
How do they get the people from the bridge before flipping it? It must take 15 minutes before a ship can pass…
Flip it fast enough and the problem takes care of itself… Whee!
That’s on the cover of my Mechanics of Materials textbook.

The back cover has a picture of the bridge in the up position.
You’re not thinking with portals.

“and four if he’s drunk”
Wow man, here in Quebec we got other standart of drinkers! It could long 4… hours!
Hahahahahahah tellement
(I’m drunk right now, that’s funny)
I put on my O face when my boat goes through.
:O That’s my hometown bridge! How dare you put it on Failblog! Lmaoo!! Although you do have to walk a mile to get over it…. If you’ve ever seen the bridge go up, especially at night, it’s quite a beautiful sight
It’s gorgeous!
Relax. It is a win.

not worthy of a post
Okay, that’s just a little bit scary.
looks cool but it is a major fail as the tall ships can’t travel up the tyne now which is a pity.
That’s why it rotates….
It still lets the big s**ts float out to see though.
SEE! WTF SPELLING FAIL.
There are barriers and a warning buzzer a few minutes before anything goes under it lol
also it only opens at given moments of the day. any1 who’s ever visited newcastle even just once (like myself) saw the sign with the opening hours.
don’t really see why it’s a fail.
Read the title. It says “WIN” twice
YOU are the fail.

Ever wonder where the money for proper infrastructure goes?

oh a stoties!!! which are a type of big bread bun.
Well not everyone can *walk* up stairs bright spark.
I wasn’t aware that motor vehicles were capable of climbing stairs. Also, such a structure would be extremely susceptible for bad weather.
Look up the Sage Gateshead and the Baltic contemporary art museum. Both those rather beautiful buildings are right next to that bridge. The idea you suggested would look ridiculously out of place and compared the the other bridges on the Tyne would spoil the look and feel of Newcastle’s quayside.

Ever saw a boat with really friggin tall mast?
I miss the Toon as well… Cheers pride of the North!!1
This bridge is over 10 years old. There’s no reason for it to be posted now, unless failblog is retarded as hell.
Even though it might be 10 years old as somebody says, I haven’t seen it before or still don’t know where it is.
I hadn’t seen it before either. It’s the Gateshead Millennium Bridge, linking “Gateshead’s Quays arts quarter on the south bank, and the Quayside of Newcastle upon Tyne on the north bank” (per Wikipedia), but that still doesn’t mean anything to me (except it’s somewhere in England); however further research shows that Gateshead and Newcastle upon Tyne are communities in the northeast part of England, not far from the coast.

Very nice.
It also lights up in a cycle of colours during the night. Google image search Newcastle quayside or millennium bridge for some stunning photos.
Wow how nice –thought it was a photoshop at first! Also love all the math geek comments at the beginning. Nice to see art trumping utility occasionally. Thats why we started painting those cave walls in the first place.
“Can we make the Jump?”
“No Jump but if we go fast enough centrifugal forces will hold us to the curve…”
This is why this bridge will never be raised for a chase scene.
Whats even more remarkable is that it makes the sun come out whenever its raised.
And if you`ve ever been to Newcastle you`ll realise that it doesnt get raised very often!
I know that bridge… and it scares the hell out of me walking over it…
