Isn't U6 6086 alloy, not 6066...

Amazing vibe to that video. Way too much pissing though

The seat tube is black dude... Nice video, would like to see a full length street/bit of natural video though.

Awesome stuff, but don't get too carried away, the rear disc mounts aren't designed to put up with that sort of abuse. I've heard of a few XC/mtb frames snapping the disc mounts off after a bit of trials play.

HA my missus says that aaallllll the time. But she has actually started swimming weekly now, just weird pervy guys putting her off

I'm torn... I'd probably go for the car if I could take my best mate with me, I can imagine getting pretty tired after a few hours with the bird hahaha

Really nice video, and some awesome riding. Vancouver looks like a beautiful place to ride! Lots of spots with lots of variety by the looks of it.

I swear paying fortunes for old bikes should be almost as uncool as collecting stamps.

I know these are quite old but I got too interested not to reply ha Scramjets will never be used for anything other than missiles, possibly on spacecraft, but certainly never on commercial planes. Firstly they must use a rocket motor to reach a high enough speed to begin supersonic combustion, once started all the ones flown so far have run for a very short amount of time. Aside from this, the main issue is payload weight. They simply can not be designed to efficiently carry weight particularly to travel any distance because the amount of fuel required becomes hugely prohibitive. I'd be extremely surprised if you didn't see it again at some point. All it needs is the correct economic situation and state support (i.e. a pan-European project) and SST can become economically viable. No one will design a commercial plane that cruises at transonic speeds. The drag between Mach 0.8-1.2 is significantly larger than above and below those speeds. You design a plane to cruise at subsonic or supersonic speeds not in the middle. Airliners as you know them now will not go much faster than they do currently, they will only do it more efficiently. The SR-71s weren't pushing the envelope "just that little bit further". They were rewriting the book on super....supersonic aviation! Since then high temperature materials have come along a huge amount too, not to mention the Russians would be much more willing to sell their finest Ti when they know it's not going to be used to peek over their fence! The first of your points is fair enough for a plane flying THAT fast, plus the skin was actually rather thin in a lot of places. The markings around the cockpit etc are there to warn ground crew not to lean on them in case it's bent! The third about the misfiring, that's a problem they actually solved after it was discovered. They developed flight control hardware that could detect a inlet unstart before it happened and compensate accordingly. Unless I'm getting confused between something else you're talking about the D-21 which was launched off a still experimental A-12. That was a ramjet and it didn't explode when it hit the shockwave, it seperated badly and hit the mothership causing both to crash. The crew ejected and survived but unfortunately the navigators pressure suit leaked and he drowned. Scramjets don't work at less than 3,500mph The "G" at 5000mph would be irrelevant. It's the acceleration that causes that stuff, and since you need a rocket to accelerate to the appropriate operating speed, yes there would be significant acceleration on your body! Possibly beyond Space Shuttle levels! The cost in fuel per hour would be nothing, literally nothing, in comparison to the maintenance costs. Although it would be cool to have your own fighter jet haha. I don't know of any supersonic light transport planes though...

The guy states water and electricity is the fuel for starters. Then goes on to say the process uses electrolysis to "break the water down". It's basically a hydrogen powered torch/car that processes the water on board rather than in a plant. If there's any innovation there it will be in the electrolysis process, there's nothing new about burning hydrogen (just ask the Hindenburg )

If you're talking about the shaft the drum spins on then it won't be experiencing a torque. If we're talking a driven shaft then the torque is pretty easy-peasy anyway! First, just need to calculate the moment exerted by the cable. If you want to impress your lecturer you may want to do calculations for a fully reeled in cable and completely reeled out. Whoops read your post properly and you already have a moment... Other than that, there's plenty on the web, (I've just had a quick look on google, "torque stress equation" brought up pretty much most of what's in my notes in the first result) to help you answer it, not to mention I'm sure you have your own notes. I'd be chucking in stuff about wind, earthquakes and anything else that will make your analysis stand out from the shitmunchers for max credit too.

He's in London most of the week. You'll need to make an appointment first.

The Navy is tempting after Uni, they offer silly amounts of money (like £35,000 golden hello) for graduate engineers The missus would flip her shit though

Currently run a BB7 but have to say I much prefer the feel of Hopes.

Having it on the following weekend means it won't clash with any comps as well. Another vote for 22/23 May.

I'd advise you to ring Tarty on Monday and see if they can get hold of a left hand Middleburn for you. I may be wrong, but I think they have a pretty cushty relationship with Middleburn.

What is it with Linux users and suggesting the most long winded solutions to any IT problem? My housemate last year was exactly the same, very knowledgeable computer guy but never a simple solution from the man!

McLaren have officially announced they've abandoned the ride height system they were pursuing after the FIA's clarification although they haven't ruled out something altogether.

When did Rachel Atherton get not ugly?

She's hot even when she's squatting to take a shit in the woods!!!

Looks like you got some nice camerawork to go with that nice riding there

Really good example of fatigue failure on the chainstay plate! Classic beach marks

A bit of a null point but I'd reckon brakeless puts less stress through the FW as there's more rolling engagement than pure preload and stamp on the pedals sort of technique
