# Force equillibrium problem

## Homework Statement

Harry the painter swings year after year from his bosun’s chair. His weight is 575 N and the rope, unknown to him, has a breaking point of 300 N. Why doesn’t the rope break when he is supported as shown at the left below? One day Harry is painting near a flagpole, and, for a change, he ties the free end of the rope to the flagpole instead of to his chair as shown at the right. What happens to Harry and why? (2 pts.)

## The Attempt at a Solution

To be honest I'm entirely lost. It is more of a conceptual question and I believe the answer may have to do with the forces cancelling each other out. I also believe the rope will snap when on the flag pole (or the pole might) because of the uneven forces.

We need the pictures.

In the first diaram, there are 2 forces(cables) pulling the man.
In the second diagram, only one force pulling the man.

That still doesn't help much.

If 2 identical cables are twisted together then the strength(breaking point) must be double than that of a single cable.
