Hopefully, I can frame this question understandably.
In our standard garden-gate configuration: Consider a traditional right
triangle with side A (vertical) & B (base) with hypotenuse C. If a mass is
attached to the BC end, I assume that there is an applied force to keep
point AB against the pivot, whichever method is used there.
My question is, "Does it matter what the angle of the hypotenuse is? Would,
say a 30 degree angle work as well as a 45 degrees, or is there a cutoff
angle to maintain the horizontal force against the pivot?"
This could directly affect the height of A when constructing a Lehman. Of
course, I think I remember (its bee a long time!)that an equilateral
triangle is more stable. Therefore, I assume it might depend upon the
length of the arm (BC).

Consider a=20

My question is, "Does it matter what the angle of the hypotenuse =

Would, say a 30 degree angle work as well as a 45 degrees, or is there a =

angle to maintain the horizontal force against the pivot?"
