I need help knowing if I am selecting the correct wood beam.
The load will be all near the center and a 250 pound man will be doing pull ups on it. I would estimate a 1,000 pound dynamic load to be safe.
I am looking at a 3.5in x 12 in x 20ft Big Beam (LP makes it, it's an LVL). It will only be supported at the ends.
How can I calculate the correct beam size? Thanks.
