Is it supporting one floor or two? What about an attic? What is the joist length on each side of the beam?
It looks like the payment failed. Do you want a phone call?
Ok. Let me run the numbers on that.
That beam is undersized
It will work at 13'-5" only if it's southern pine no. 2. How much it's over otherwise depends on the species and grade. For something like Doug-fir no. 2, it's over by approximately 25%.
