Hello. I need to build a structure to hold a 2000 lb centered load. It will be 11 ft high with a span of 24 feet. I am thinking two wooden columns and a wooden beam across. What size beams do I need to use? Thanks.

Hello. I need to build a structure to hold a 2000 lb centered load. It will be 11 ft high with a span of 24 feet. I am thinking two wooden columns and a wooden beam across. What size beams do I need to use? Thanks.
First, start with the following webpages:

Thanks for these links, but I still need help sizing the wood beam. I am not familiar with the different sizes and types and their respective properties.
Ok, see:

So, using a 4 x 10 with the load applied at a single point and parallel to the 9.75" length, here's what I got.

Lots of deflection and stress (too much) I would change the span distance closer, stronger material or re-evaluate your requirements.
Why wood?
