What am I missing on beam design? sandwiching 2x6's to make a beam is
not correct???

Not really, it is a waste of material resulting in a heavy and weak beam.

Find a Strength of Materials engineering text and learn an understanding
of the term "Section Modulus" and how it applies to beam design as a
starter.

Challenging looking stuff to say the least...
I hope this doesn't keep the kids from getting a swing set!
