Was reading this with a lot of 'purring' and it all fell apart at the end.

How on earth can you design a racing car, realistically, that has no adjustable geometry?

I think what I hate the most about it is how it screams 'Formula Textbook' and not real world.

Yes, it'd be really nice if we could get all lines of force to follow the load members perfectly and completely eliminate crank/torque moments, but you can't.

So instead of the judges punishing a design that offers adjustability, why not force it and offer the points for how well that adjustability is designed?

 

Do you think rod ends in bending is ok ? There are many proper solutions for adjustable Geometry that dont cause the rods to snap. Rod ends in bearing are unsafe, they are marked down by judges for good reason!

I crashed our 2004 car due to a broken rear pushrod on the accel event

 

Read the article again. Teh advice is to remove the adjustability which isn't practical. If you haven't specced your materials and design right to deal with the load or you rotate the rod ends so that they are receiving load incorrectly, then that is a complete feuck up and not what I was on about.
