If a span is 180 degrees it has infinite force on it. Even zipline and electric wires have sag in them. So 170 degrees is 5x the force as what is applied in the middle. I thought an American Death Triangle put magical amounts of forces on the bolts and anchor material since the top line is 180 degrees. Come to find out it is not that bad.
