Homework Statement: I have a 80 foot tree weighing 4000 pounds ready to fall on my cabin. How thick of a cable or a nylon rope a do I need to stop it from hitting the cabin?
Homework Equations: m=f/g
I am 82 years old and can no longer do the math on this real problem I have due to a brain injury.

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.
