Hello everyone,
Just wondering how I work out the angle on a Artificial High Directional.
In the photo, the angle I want to work out is between the metal Gin Pole and one of the tie downs connecting it to the hand rail, lets say the Yellow one on the front / right.
I'm trying to figure this out with out using a Protractor.
Can anyone help please?
Thanks,

Hello, thanks for such a fast reply!
The Gin Pole is 90 degrees, straight up.
Obviously angles play a massive roll on Rope Rescue so with every system we rig, I need to work out the forces on the system.
But - want to be able to do this without a protractor.
Thanks again.
If the gin pole is straight up, the solution to the problem you've posted is:
Let
Let
Let
Then
So, just divide the distance from the knot to the gin pole by the length of the rope and press the button onyour calculator.
REMARK. I understand that you may only have a given length of rope, but need to make a certain angle. In this case, you'll use the same formula, but a little algebra and trig will be necessary to solve for one of the unknowns.
This will work for any length of rope at any distance from the gin pole, AS LONG AS THE GIN POLE REMAINS VERTICAL.
