I dont think you can blame the crew for Hamilton's stop. The front jack failed. The mechanic tried again and it failed again. Then they brought in the replacement.
I wouldnt say that is the crew's fault.
It's not the crew, it's the team management. Apparently the jack has been causing problems in practice and it was only luck that it hadn't failed in the race yet. And yet they still used it in the race.ecapox wrote:I dont think you can blame the crew for Hamilton's stop. The front jack failed. The mechanic tried again and it failed again.

My thoughts exactly...The fault goes to the aspect that they have been using an item that has a risk of failing...More that on a race day.

Right, because they almost certainly had done their calculations... time gained over the old jack design – 0.3 seconds, number of pit stops between failures 80*, time lost in a stop if it fails 12 seconds...myurr wrote:It's not the crew, it's the team management.

True, the pitcrew hardly had anything to do with it. It does show a little bit of a panic reaction from McLaren regarding their pitstops. They soon found out there was a problem with the pitstops, so they created new procedures and developed a custom new jack, similar to what Ferrari was using since the beginning of the season.ecapox wrote:I dont think you can blame the crew for Hamilton's stop.

All items have a risk of failing, it's a matter of ballancing that risk against the time gained by using them... It's Lotus' (old Lotus) philosophy down to a T.Poleman wrote:My thoughts exactly...The fault goes to the aspect that they have been using an item that has a risk of failing...More that on a race day.

Well, I'll repeat myself from earlier – again – their earlier pit stop failures this year were caused by lack of new tech, not by too much.neilbah wrote:cool, and i didnt slate the macca crew, just the technology, gizmos, wheel nuts, jacks, traffic lights, boards on te mechanics arms....and all im asking is..is it worth it? the gains versus the losses, i may be wrong but i make that the 4th holdup lewis has has in the pits this year and maybe 5 or more if you include jenson?
If the jack gains 0.3 seconds a stop (pretty conservative considering it removes the need for the jack man to step out of the way before the car goes, then you're talking about... and average of 2.5 stops per race per driver, 20 races, 2 drivers... that's 30 seconds over the course of the year. If they expected 2 failures in the entire time they used it this year, then they were on a winner.neilbah wrote:the jack may have gained them a couple of seconds all year in total, well well done its cost alot more than that in one go. I stand by my point, ferrari pulled away with the fuel hose attached trying out the traffic lights, many laughs ensued , lewis had a right rear problem in canada 2012, isnt this with the new wheel nuts?
alternator and kers have no connection whatsoever.The source of the failure is to be found elsewhere ..Alternator 12V -Traction wrote:Is it possible that the alternator received to much current from the Kers? An alternator will overheat with too much charge/ current and considering the alternator handles/directs the energy back to the engine it might be that it might be possible. No?
It's not as simple as that. The 0.3 seconds gained here or there is unlikely to gain them places. A 10 second loss like today is almost guaranteed to lose them places.beelsebob wrote:If the jack gains 0.3 seconds a stop (pretty conservative considering it removes the need for the jack man to step out of the way before the car goes, then you're talking about... and average of 2.5 stops per race per driver, 20 races, 2 drivers... that's 30 seconds over the course of the year.

Except that the truth is more complex than that again – 0.3 seconds gained on each pit stop is very likely to gain them a full place in 100 odd applications of that 0.3 second gain. A 0.3 second gain in canada for example would have gained them the place. Is it likely to gain you a place twice in 100 pit stops? Entirely plausible.myurr wrote:It's not as simple as that.

So your simple sums hide a much more complex truth, and that is that yet again operational mistakes, wherever the eventual blame for that may lie, have cost McLaren more points today.

Rosberg made the softs last nearly as long and didn't loose as much time. Clear then reverted Schumacher to plan B which I assume was the two stop strategy. His performance on the mediums in the first stint kept him in touch.
