google brushless motor efficiency, look at images if you don't fancy reading.
i said rarely. consider that in f1 the clutch is to be operated 4-5 times. once at the start, two or three for pit stops and one left over for emergency/unforeseen events.
once again, you don't need a clutch for an electric motor, whether it is mated to a gearbox or not
Yes... Don't see your point? The gearbox is necessary so that the motor operates near peak efficiency as often as possible. Considering f1 cars rarely stop, it's not a significant problem to forgo a clutch
A clutch isn't really necessary, i'd guess.
and it will get floated every couple of years until they figure out how to make it worthwhile
the whole "max torque from 0 rpm" phrase that is thrown around is quite misleading. While true that a motor exerts its maximum torque at zero rpm (and drops linearly as rpm increases), it also has the worst efficiency. maximum power draw (it's a short circuit!) and minimum power output (it's not moving is it?). peak efficiency is at a specific rpm, thus a gearbox is needed *for efficiency*.
to put 8 kW/kg into perspective, all commercial brushless dc motors are at 4 kW/kg and it is a limitation of the materials used.
Commercial internal combustion engines range from 1 kW/kg to *maybe* 3 kW/kg if it is turbocharged to the point of sacrificing engine longevity and formula 1 engines are at around 5 kW/kg
although i suspect they saved weight by using the vehicle frame as (part of?) the stator, a perk of making a motor for a very specific purpose.
you do realise the absurdity in what you suggested, don't you.
can you think of a way to do those tests with less cost?
but to see them actually go for it?
going off on a tangent, whoever is responsible for android's ui needs to be tortured.
no clear indication of accepted taps, no indication the device is busy, no way to distinguish interactive elements from eyecandy, menus needlessly hidden even on huge devices, pointless separation of menus (eg: why are there two menus with different styles in youtube?), elements abruptly changing location whilst being active (you tap somewhere but at the last fraction of a second, the list refreshes without warning and now you must guess what you've tapped), message windows pop up just before you tap something completely unrelated but since you've already tapped the window disappears and now you will never know what it said, i could go on.
my 1997 hp48gx has immeasurably better engineered UI.
*tortured* i say.
If you have the patience, can you please give me a short explanation how to read the chart? Thank you in advance.
... do you have a source?
"They want to consume more than they produce"
if you were familiar with what the EU *forced* us to do when we entered the euro, you wouldn't say this.
they basically paid us to stop exporting.
there doesn't have to be a provision
they can just make it so the greeks will wish to leave the eurozone.
Only through hard work and perseverance can one truly suffer.
