Hello ,

I got a problem and have been trying to solve. Considering a cable (hanger) that has boundary conditions as pinned-pinned or fixed-fixed. I am trying to evaluate the stress in the beam element, as previously suggested to use bolt pretension which solved the tension issue. I got 2 questions and I hope to receive answers about them:

1. Why applying bolt pretension force calculate accurate solution however force applied at supports gives wrong solution?(attached pictures 1,2 are for bolt pretension ,3,4 for force )
2. If I am willing to apply a horizontal force component or moment at the lower part of cable. What form should I introduce the force/ moments? as a nodal force or?

I appreciate your support and hope to get a response

You can fix one end and apply force/ moment at the other end.
