Why do automobiles with more vertical rear windshields have rear windshield wipers?

Like minivans, and those ugly boxy cars. Boundary layer separation?

# Mechanical

Mechanical

I need to design the end tips of a gripper that will pick a car roof stiffener. When by accident there are 2 stiffeners on top of each other, the tip should reject the bottom one, and take the top one. There is 5mm distance between them when they are put together by accident. I thought of a design that would pick top one, and leave the bottom on the jig, but it wouldn't pick the stiffener if there is only one stiffener there as in 99% of the cases. Any suggestions?

# Matlab Question

Matlab Question

I'm trying to understand "interp1" but I think basic English is my downfall.

Here's matlab's definition.

So I've got A= [1 2 3 4 5 6] & B=[7 8 9 10 11 12]

I've got a value 1.5 from data set A, how do I get matlab to give me the coorisponding value 7.5 from data set B using interp1. (my professor can't explain it better than matlab forums)

# Na + H2O engine

Na + H2O engine

Just a thought experiment. If you could. How would you build an engine with sodium and water as the power generation?

And let's say while it's off, you use solar power (or something) to get pure sodium back. How would you get the pure sodium back after it reacted, with as little waste as possible.

Any flaws with this concept of building a completely green mechanical and not electric car?
