Topband: getting it up

[Alan Downing]

Hello Gents

Thought I would change the subject from band plans.

A 150ft tower laying on the ground and anchored at the base. For calculation
say the total weight is 1000Lbs.
If pulling from the base end at a height of 15 feet with a winch rope
connected at the 150ft point what would the tension be at
Initial lift.
+10ft
+20ft
If the rope was connected at 100ft from base what would the tension be at.
Initial lift.
+10ft
+20ft
Any formulae for same would be much appreciated
I should have paid more attention at school.

Many thanks in advance.
