'Theres no such thing as mechanical grip'

What do you think πŸ€”

According to race engineer,Frank Dernie πŸ€”

'Dampers are not shock absorbers'

Well, he's right through and trough: you have no idea how pissed was Newey when he came in Rome to my University for a lecture. He got asked "what you think of multi-link suspensions to increase mechanical grip?". He laughed and said "There's not such a thing as mechanical grip, lad! You just get the tires hot enough and under pressure enough to let the rubber do its job!"

I wouldn't say it's entirely true that dampers aren't shock absorbers.
It's true that the spring's primary function is of a shock absorber and a damper's is that of damping / slowing the rate of load transfer / speed of compression (and decompression on rebound).
However by the very nature of the damper slowing movement speed it is therefore resisting movement and so absorbing the force against it to some extent.
In what ratio it does this compared to the spring at general / extreme settings, i don't know - it could be fairly negligable. It depends on the setup. With a rock hard spring and a super soft damper i'm sure it would be negligable but with a super soft spring and a rock hard (slow) damper i don't think it would.
But i am ignorant, so educate me.

Don't forget that the tires are part of this soup. Both the tire pressure and design of the tire have an effect too.
If it's not grip brought on by aerodynamics.  What would you call it?

Wheel grip.
That's how is called in engineering.

So there is mechanical grip but it is "properly" called wheel grip?

Okay learned something new.
Thanks Lord.

Do a search for "race car mechanical grip" and quickly see there is lots of belief in it as a proper term and as a real effect. Check F1 Dictionary for instance.

Do a search for "race car wheel grip" and get ads for steering wheel tape.

They could have said the same thing as Lord, "Engineers call it wheel grip."




:D

It's just playing with words. Ofcourse only the tires will give grip in the end.

But how this (tire, or if you will wheel) grip is achieved through the suspension setup, is called mechanical grip. Ofcourse there is no such thing as mechanical grip technically, but the term is simply used to make a distinction between grip achieved through downforce/aero adjustments (for higher speeds) or mostly through the suspension setup adjustments (for slower speeds).

That's how I understand/read/hear it. Grip is grip, achieved or improved mechanically or aerodynamically, through the tires. Correct me if I'm wrong ;)
