Torque roll

I know I can get a few degrees of roll from my car by gunning the throttle while the car is at a standstill

I was just wondering how much the F1 did this, if at all?

I'm don't think you are using the right terminology. A car cannot torque roll the same way an airplance can.

A car cannot torque roll the same way an airplance can.So I'm just imagining the sideways roll in my car when I gun the throttle while it's standing still?

Diesel powered 18 wheeler trucks tilt a significant amount when starting from rest due to the torque of their engines.

So yes, this does really happen.

Imagining it could be a possibility. Or you could have a serious torsional rigidity problem with your car. I have never experienced any kind of torque roll in a car when it was launching from rest. But I have seen some pro-stock and top fuel dragsters twist in the frontend, but not a full on roll of the interior body.

What car do you drive? Just out of curiosity...

Imagining it could be a possibility.I am well aware of how vehicles function and that this torque reaction is present in just about EVERY 4 wheel vehicle that has a longitudinally mounted engine. It is more prounounced in some vehicles than others. It doesn't happen on launch -- it happens at rest while the car is not in gear.

I asked a simple question and I'd prefer hearing from someone who's driven an F1, and who could personally confirm or deny this this. I do not need someone who first denies that there is no such physical effect, and then proceeds to speculate on it.

If you don't have anything constructive to add, then I don't have any further reason to discuss this with you.

no its not something you feel in the f1. you can rev it in neutral and it will not move the body at all. you will just feel and hear the vibration and noise build up and die down very quickly but you will not feel the car rock sideways or even twitch at all.

no its not something you feel in the f1.Thank you =)

Wow...Relax, guy. There is no reason for you to feel offended. We are all friendly here.

torque roll depends on a couple of things
it's a force F (in Newton) multiplied by the arm s (in meters)
the arm is the distance from the center of the force to the turning point, and is in a car very small, it's the radius of the crank.
the force is calculated by the formula 1/2*m*v^2, with m for mass in kg en v for speed in m/s. as you see there is a mass involved, and especially with sportcars with lightweight compact engines, that mass is a very small one. with a truck, the arm and the mass are much greater, since they don't need a high revving engine (the higher the revs, the lighter the parts) and therefore their torque is much bigger, and it wil roll the car a bit.

If this is directed at me: I'm a mechanical engineer, I know the dynamics behind it ;)

I just didn't know how much actual angular displacement a F1 would undergo due to this. Since I don't have any numbers to go off of, I can't sit down and calculate it.

it's not directed at you in particular, it's just a quick and simple explanation for torque roll.
a mclaren would probably get even less torque roll due to it's relatively stiff suspension set-up...
i'm studying mechanical engineering but i've almost decided i quit, it's just not my thing.

Don't forget the low inertia of the F1's engine due to a lack of a fly wheel...

Just my :2cents: but engineering courses always start out really boring and with no real sense of what you are achieving. It all becomes worth it in the end though ;)

true, but i also have to figure out if i want to pretty much calculate loads of stuff over and over again, i'm just too shortsited for that, i want more to design shapes and superficial things than the internal bit...
but that's a decision i have to take carefully, and i'm thinking a lot about it.

edit: you are able to raise my motivation level by getting me an internship or just one day of wandering around in woking, i'll travel to do that anyday :naughty:
