Two point anchor loading

How can we work out the highline tension and anchor loads resulting from a suspended mass?
Divide the system in half and look at the forces applied and required to keep each anchor point stationary. ;)

Great video Richard. I would love to see a similar one with three or more anchors, both in a 'Lab' setting and more real world, with imperfect equalisation.

In other words, the tensile force T in each leg is F / (2 sin D) where F is the weight force of the mass and D is the angle of deflection (from the horizontal) of the legs. T can get quite large as D gets smaller.

question. so the last example we had an angle of roughly 160 degress why is it that theres only 150% on each anchor while rope theory tells us it will be 300%

What he is trying to explain is the use of scaled vector diagrams. Where it is loosing a little is the estimation of the hypotenuse piece. If you are going to use this method the diagram needs to be properly scaled. Instead of drawing a little triangle in the corner starting from the bottom of the sag and create a right angle triangle by dropping a line straight down from the anchor. then simply measure. Divide the Hypotenuse (long side) by the short side and you will get a percentage of load going to anchor. Closer to zero degrees of sag the greater the force on the anchor. Still a great explanation.
