Yes, I used to marshall Moto X back in the 70’s, but rope and sticks at least have some give... more than steel wire and girders anyway.

Not the stake I hit at Boraston...

Russell confirmed as Lulus replacement.

@ukracer . See you in the welders arms. I will get them lined up at about 8.

Different configurations were tried and tested and these were anchored to snap posts, in this configuration you had the Armco barrier at the front, this was connected together with various uprights which went varying distances into the ground, the two or three wire ropes were connected to the upright posts and connected to the snap posts, if a vehicle slewed into them they hit the Armco and snapped the upright posts at ground level and the Armco deformed and both absorbed a lot of the impact forces, the two or three steel ropes then absorbed the forces of the Armco if it was a severe impact from heavier vehicles such as a lorry, if the loadings were so great they snapped the snap posts at either end which has short wire ropes to prevent them flying.

I often see just wire rope as the barrier, no Armco, up the M1? M6? not sure where, cannot have been tested with motorcycles in mind!

I often think about the wire rope barriers too... they look pretty sketchy, although no doubt designed well enough for smooth sided vehicles. But obviously a death trap for a motorcyclist.

Not sure why the hate on the armco... it did what it was there to do, absorb energy and stop the car spinning into the spectators etc... he walked away alive by virtue of all of this technology developed in the last 100 years... pretty good result I think

Drivers reactions:

Vettel: everyone ok?
Bottas: everyone ok?
Verstap: did they get out?
Leclerc: is he ok?
Hamilton: damn that start was good...

If only Hamilton was so honest all of the time...

An interesting situation no matter which angle you look at it.

It's an opportunity to for Mercedes to have a real life test of a driver without having to commit.

It could massively affect George Russel's career in either direction. If he qualifies in the top four then everyone will know the potential he has but if he puts it tenth on the grid then people are just going to highlight the fact he couldn't get the fastest car on the grid to the front. It's going to be a tough few weeks for him.

If think that it's a little unfair the way you reported that, the first thing Lewis said was "Everyone ok?"

I am not happy with his latest crusade. I think it's OTT but to be fair 1. He probably did not see it in his mirrors like leclerc did but his first words were Everyone all right.

Unlike the rest of 'em, he was quite a way up the road, so can't imagine he did see much in his mirrors - and why watch his mirrors for stuff at the back?

 

[badabec]

I always follow Hamilton, Russell, Albon and Grosjean. Lando not so much.
Hamilton came from working class background, Lando's father is one of the richest men in the UK. Albon's mum, fraud. I don't know about Russell.
I don't care what they do off the track. I never watch any of the race preamble. I start watching at 9 minutes past 2, stop when they cross the finish line.

Well, I am a lapsed fan. Anyway, I did post the video so you can see what he said.

For my money, saying "damn that start was good" is an insight into how concerned he really was.

Good old jolyon, late to the party as always.

Sky update on circuit and barrier, also Romain thanks helpers.

A problem with the TV coverage is the camera angles. The Tilke designed tracks have very long straights and a camera pointing down the straight shortens it and you don't get any impression of speed. This year, with some of the old fashioned circuits coming into use, the camera angles showed a bit more of the speeds involved. Going uphill at Eau Rouge in Belgium is one of the best shots.
Better coverage of the mid field would help but they have always been ignored. I can remember coverage of one race in the 70s, all they showed was the two Lotus cars, line astern, for the entire race.
Showing the speed superimposed on the halo has helped, especially when braking, I just wish they would use dials, not numbers.

Hamilton will be kicking himself as hard as he can he rattles around in his luxury penthouse, suddenly F1's no longer the Lewis Show [all about me ] as someone else gets a chance to shine.

That said, I don't grudge him his success as he'a brilliant pilot, but it's almost become "Do as I say or I'll shame you into doing it", It's just, as a sport which needs widespread popularly and the revenues such generates, in order to survive the huge amounts of cash with which it's awash, it has for years become...well...processional and a bit boringly predictable.

This from someone who never missed a race, even getting up in the middle of the night to watch the Japanese race live.

I say take it back to Group B style crazy mental cars with few restrictions and rules. Just make em safer so folk don’t get hurt when it goes wrong

In a fuel (petrol) fire it is a very rapid fire in which the vapour is ignited, the heat then turns remaining fuel into vapour and this burns and is basically a small explosion as opposed to a fire.

If you ignite diesel its actually the diesel and not the vapour which burns which is why its atomised through diesel injectors in an engine, it burns much more slowly and more thoroughly.

With the battery packs you get issues, with Li-On cells they are prone to self combustion and this is through heat damage or a pack not particularly well constructed, if one cell overheats it can self combust and if any part is ruptured it can burn as well as damage the surrounding cells to the point they rupture and spontaneously combust and this is a major issue with battery vehicles as they combust and don't need oxygen or anything else; race cars are in open air and have lots of oxygen and to stop combustion you remove the fuel or oxygen, or cool it down to the point it won't combust. For traditional fuels you only need remove the fuel or oxygen and heat then the fires out, and various types of fire extinguisher exist and each has its own positives and negatives.

In a lithium cell fire you cannot extinguish it without some very specialised and expensive equipment so once they combust thats it, put water on them and it accelerates the combustion and makes it worse. Lithium ion cells are built on giid matrices and this is how they connect individual cells together to make a block, they then connect numerous blocks together to make a complete battery pack; currently they are looking at altering the grid matrices from plain strap to tubular matrices so they can pump coolant through them and a radiator to prevent individual cell overheating during rapid charging and discharging cycles to prevent overheating and spontaneous combustion, and this is why I raised the issue.

In an F1 car they use hybrid technologies and lithium ion cells and this is why I raised the point, we know his car was torn in half so did this damage the cells, and did the heat from the fire damage his cells?

If you look on You Tube they have actual videos of electric car self combustion and on Top Gear there is a video of Richard Hammond losing control of an electric car and this going off the cliff, he walked away but the electric car self combusted.

years ago I did lots of testing with F1 cars and engine fires at MIRA. The fire is bad but fairly obvious. What’s left behind is much much much worse and has caused serious injures many days after the fire is extinguished
