Problem

We have two carabiners anchored in a rock, both at the same height and at a distance of

d

from each other. We snap a loop with the length

l

into the carabiners. Then we snap another carabiner on the loop, from which we would like to abseil, while applying a downward force of

F = 2.0\,\mathrm{kN}

. Calculate the tension in the loop and the force that will act on the carabiners, in cases where the abseil carabiner is slung on one and on both parts of the loop. In which case is the force acting on the loop lesser and which case is safer?
