G forces across the decades

Post

How do the G forces that current F1 drivers undergo compare to those suffered by drivers from previous decades (for example Fangio in the 50's)?
Have maximum G force loads decreased since Senna's death because of circuit alterations?

Interesting question. I doubt it was measured in the past, but a look at average speeds would be an good indicator.

ps - that big writing looks like shouting.

G-forces from 50's-60's to early-mid 70's are NOWHERE near what is experienced today.
2010's cars are probably able to develop the highest G-forces ever.
Early 80's cars were somewhere around 1998-2000 cars in DF, although one have to remember that with stick-shifters and no power-steering the cars were EXTREMELY tough to drive back then.
As far as circuits go, we still have fast corners on many tracks so not much changed in that regard. Usually fast corners were eliminated only if there was no proper run-off.

I guess the cornering capability of an early, skinny-tired non-downforce f1 car would be similar to a present day Caterham/Westfield on sports tires; about 1.2G.

but what about here

http://en.wikipedia.org/wiki/Lotus_88

The Lotus 88 with ground effect. What g-forces were they pulling then inside that car compared to today

I would guess less than that those tires sucked. A modern race slick is literally decades ahead of those tires.

1.2G is what I can get from 185 width Toyo T1S tyres on my Westy (these are 'normal' tyres, -not the barely legal 'track day' type tyres... I'd imagine early slicks would be at least comparable...

As lateral accelleration (meter/s^2), or g-force, is defined as speed (meters/s)^2 over radius (meters), it is fair to say that
"g-force" increases with the square of the speed. Twice the speed through the same corner gives four times said g-force.

When cornering speeds has gone up enormously since the 50s, even Fangio would have had problems with an F1 car of today.

But that's not mentioning g-forces from breaking, which would surely had left the poor man breathless with this year's cars.

They werent slicks though they were hard some what treaded tires. Image I would venture a guess that even modern street rubber with a wear rating was better than the tires of the 60s

Just for reference, if you can manage to go through a roundabout with a 50 m radius at 88 km/h (55 mph or 24.5 m/s),
you will xperince the sensation of 1.22 g lateral accelleration.

This might be obvious but can easily be overlooked; put another way; strap yourself into a seat and get a few mates to pick the seat up and tilt it on its side; that's equivalent to 1G laterally and its really quite amazing how much force it is... 4g or even 6g must be amazing...

I wonder what G-force a modern rollercoaster obtains?

There are rollercoasters that can pull over 6g.

Surely the analogy with a roller coaster is the point.
If the fitness needed to survive high g forces for around two hours is the main requirement of an F1 driver, then how much of the old skills has been lost and replaced by technical tricks within the huge raft of regulations designed to layer the illusion.
In other words, how different is driving an F1 car now, from spending time on a good roller coaster and then racing in virtual reality in simulators?
Would save a lot of money.
