What is that in feet? :lol: j/k

Yes, that's pretty steep. I did some research and the steepest grade on the U.S. Interstate system is 8%, and I have driven it (I-24/US-41/64 Westbound over Monteagle Mountain, TN).

Where is that? I want to make sure I avoid it.


I hope that it's just a picture of a truck, placed there to cast fear into the hearts of anyone who attempts to drive that road.

27% grade: arctan(0.27) = 15 deg.
33% grade: arctan(0.33) = 18 deg.


So would 100% be 45 deg. or 90 deg.?

I imagine it would be 45deg where rise=run. Or run=fall. :o


Fall is right in that case. At that angle, I don't think anyone would be rising.

Edit:
Oops, my bad. Definition uses horizontal movement, not length of road.


Actually, you did say "length of road" (hypotenuse?) in your first post, but everything else involving pitch or grade is measured rise over run, so I suppose this would be too.

It's been 23 years since my last geometry class...
