In my younger days I did a
little abseiling down the side of the school to demonstrate forces in
equilibrium for my physics students. At one point in the decent I would stop in
a position similar to the person in the picture in the link below. Draw a
free-body force diagram of the forces acting on this person.
Assume this person has a mass
of 72kg, they are half way down a 12m wall with the rope secured at the top of
the wall. What is the magnitude of the force between their feet and the wall?
What is the tension in the rope?
