You can look up the properties of Balsa wood. I've done this kind of project many times. The yeild strength of balsa wood depends GREATLY on the dimensions (length and width) of your piece. The trick to making strong structures is to reduce any bending moments by supporting "flexible" pieces so that they are more rigid.
The strength of the glue that you use will also determine how strong your structure is. Perhaps the best glue out there for Balsa wood is the Elmer's Wood Bond glue (Available at Home Depot). I build furniture from time-to-time... and I'll vouche for this stuff. Gorilla glue works well too. Superglues are faster, but are not nearly as water resistant (cyanoacrylate polymerizes in water and can create WEAK bonds).

You can read the FAQ about modelling with balsa in here :)
