Another visual quiz
 

I am not sure if this is easier or harder than the last one!

What is the shape of the car that has this top and bottom pressure distribution?

And I must admit that I couldn't get the shape right by looking only at the pressures! (I just tried, and I wasn't waaaay off, but I also didn't produce a shape that was immediately recognizable as the particular car.)

Negative pressure spike 1/3 of the way back, doesn't look like it has a positive pressure windshield bump. Are we looking at something mid-engine with a constant frunk/windshield angle, like a Diablo or Murcielago?

Positive pressure at the rear? Is this a bonkers race-car?

Added a bit more detail because the center doesn't tell the whole story.

The pressure at the rear goes up for both the upper and lower surfaces. This would be my guess (and it's not right):

People sick of visual pressure quizzes? Oh well, here's the car:

Not sick, just tired. :)

Maybe space them out or do more multiple choice instead of open-ended questions?

Well it was a bonkers race-car. :D

It's pretty hard to see the angle all the way at the rear because one is visually integrating the curvature, and there is a growing error when doing that.



Open-ended is way more fun.

What a relief! I was stuck in 'production car mode'!:p

No way, keep 'em comin' if you have them. It's a great mental exercise!:thumbup:
