If you put a tension guage on the tie off line, you would find that the tension 
is essentially equal to the load divided by whatever advantage exists in the 
tackle system. (To be accurate into multiple decimal places you would have to 
figure the weight of rope, hook, and bottom block.)

If you're standing still holding the line, you are equivalent to a heavy object 
as a tie off. Tree just a heavy object with roots.
