Hello I have a problem where a wire is pulled around a half circle (disc) and then both ends pulled. The force in both ends are equal (F1 + F2). The disc must in total put up a force (F3) equal to F1 + F2 to not be pulled along by the wire. My question is how does the force of the wire act on the disc at different places. What is the force subjected to the disc from the wire at the top of the disc? as an example. Or at 45 degrees on each side? I uploaded a picture of the problem, where the red lines indicates which individual forces I want to be able to calculated. There is no movement to the wire.
