Not being familiar with "Nelson's Triangle," I googled it. That was an interesting experience; lots of stuff came up, none of it relevant. (Love triangles are N.A.)
If the rigging involves one or more triangles, the forces in question can be determined by trigonometry.

"Nelson's Triangle" is a large area in the Atlantic Ocean where there have been several unexplained rigging accidents and paranormal events over the past sixty years.
Repeatedly, rigging and lifting equipment have unexpectedly disappeared
The triangle is roughly bounded by Miami in the west, The Virgin islands to the east and the Neslon islands to the north.
Flight 19, a group of US navy Grumman fighters, loaded with rigging equipment mysteriously disappeared in 1945 in the famous triangle
The paranormal prophet Edgar Cayce predicted that inferior heavyvrigging equipment was cause of the downfall of Atlantis....that city/state that mysteriously sunk in the area eons ago.
The signs are all out there.....
