You can readily setup this situation within SOLIDWORKS in a couple ways. The first would be to create your stabilizer as a beam with fixtures applied to the ends that restrain movement axially down the angled cables. This is readily done using sketch construction geometry to specify the direction to restrain in a Use Reference Geometry fixture. You can than just apply loads to each end joint of the beam to represent your bottom load.
Another option is to use a solid element beam with links attaching the beam ends to a top fulcrum. The bottom load could then, since we are now using solid elements, be represented by a Remote Load (direct transfer) to the end faces of the stabilizer beam.
I think both of these setups, with some added fixtures for stability, could reasonably give you stress and displacement results for the situation you are describing.
If you would like to take a look I have attached the model with both these setups here as well.
THX for all.
