G-force of wind on a persons body.

After doing some work with a painter friend we were coming home and I put my arm outside of the window as we were going 70 miles an hour. Wondering what the g-forces would be on my arms and hand?

Thank you

There would be no g-force on your arm...

Presumably your arm didn't dissapear behind that car and you were able to hold it out in a more or less stable position? In that case you will feel a force on it due to drag, but it's a constant force not an acceleration so the "g-force" would be zero.

If the airstream was turbulent and your arm flapped up and down then there would be acceleration. Quite hard to quantify though.

Thinking about it some more I suppose you could say that the force due to drag _feels_ like the force due to gravity. I'd estimate it as equivalent to 3-5g.

Thank you for your reply and explanation you gave. I was just curious and you satisfied that curious thread. Thank you.
