[Spridgets] Help needed on conical washers

[Greg Gowins]

Hey everyone,

I'm having a bit of a brain freeze here.  I need to mount a trailer hitch,
and they are using conical washers with the bolts.  I should know the answer
to this, but which way does the washer need to go?  From what I remember,
the concave side should face the surface, so the washer will flatten out
slightly when the bolt is tightened down.  Is that correct?  I'm a computer
engineer, not a mechanical engineer. :)
