The tip of a 16 foot beam, appears cut at 45 degrees, is supporting a 2x6 laying flat. This is wrong correct?
I can't make heads nor tails of this.
Which is the 16' beam? The member coming in from the left or the other one?
How is the beam cut at 45°? Is the bottom of the beam shorter than the top. Top shorter than the bottom? One side shorter than the other?
You say the beam is supporting a 2X6. (Perhaps you meant to say the beam is
supported by a 2X6.) Which member is the 2X6? Is it the member laid flat below what may be the beam? Or is it the vertical member with the large knot?
Allow portions of the beam should be contacting the 2x6.
Allow what? I don't understand that.
To answer what I think you are asking . . . the beam must have proper end support of at least 1 1/2" across its width. I'm not sure which member above the 2X laid flat is the beam in question but it is not properly supported (whichever one it is).
