Dihedral Calculation Questions

[Joe Hayes]

I know I should know this but.....
If I have a rise of .625" in 36" what is the dihedral angle?
Is there a formula for figuring dihedral angles?

TIA,
Joe

Joe,
Go here online to calculate.

Answer is .99 degrees

Thanks Gordon, saved my day!! Too windy to fly in my neck of the woods
so it is working on the secret project.

Joe,
That's .99 degrees each side for a total of 2 degrees for a joiner etc.
Not much huh?
Is this a sailplane? Certainly wouldn't be enough for a dihedral ship - may
be center section of a polyhedral huh??? :)

Rule of thumb is that 1/16" (.0625) rise over 3-1/2" is one degree. Find
factor of 36/3.5 and then set up a simple decimal proportion to find X.
A hair under 1 degree.

This is a Trig problem, may have been answered. TanX= Opp/Adj Tan
X = .625/36 Tan X= .0173611
X = .9946 Degrees If I did not make a mistake. The batteries in my
old TI cal are down.

John, The internet is a wonderful thing and you can find just about
anything. Your angle is.99 degrees. Here is a wonderful web
calculator: http://www.csgnetwork.com/righttricalc.html

Opps, I should have read all the responses, since Gordon gave you the
same information.

Head hung low in the North Country,
