I have several of these trees ready to fall on my cabin back in the woods. What size cable or a 3/4 inch nylon rope do I need. Engineering toolbox.com says a 1/2 inch cable has a minimum breaking strength of 12,200 pounds. Another site says a 3/4 inch nylon rope has a breaking strength of 14,000 pounds but nylon also stretches absorbing some of the force. If I put the cable or rope 40 feet high, half the weight would be on the ground.

Welcome to the PF, Salty.

Unfortunately, for liability reasons, we can't give you advice on how to do this by yourself. You should contact a local tree service to get a quote on removing or bracing those trees.
