xluben's MAPerformance Proving Grounds 2014.1 Photos

I was driving this year, so my brother took photos with my Canon S110. Mostly shots of my car. Sorry everyone else.

Here's a link to the gallery:

John's broken axle:





My broken axle:

 

Nice photos as always ben! Wish I could have made it this weekend.

 

Can you post a close-up of the break sometime?

 

Thanks! Weather ended up being pretty decent. Looked iffy for a while.

This one? Twisted right off.

 

They must be making them out of pot metal...

 

Thanks, that's fun to see, very classic unidirectional torsion highly-overloaded (see spiral) plastic failure if I recall my materials classes correctly

 

Not very common to break the axle in two places at once though.

Usually they break off the other end and it's a lot cleaner break.



That's the same way that mine broke.

 

Nice pics. Was that the axle that dropped launching at the drag strip? Think we were watching at the time if it was.

 

That looks like a ductile failure on that side. Maybe they're heat treated differently? Or one side let go first?
