I'm planning a build of a back yard jungle gym/mini ninja warrior obstacle course and I'm in a bit of a pickle.
On the one hand, I don't mind spending more for cedar and I prefer the look, however, the availability of dimensional cedar is quite limited. Whereas PT lumber is easily available in multiple sizes.
One key consideration is whether an 8ft span of 2x6 cedar will hold up to being used as the side rails of a monkey bar since that is the largest board Home Depot and my local lumber yard carries. I expect kids and adults to be using this structure.
I've reviewed span calculators, but I'm not sure if it's applicable to a point load like this where, for example, 200lbs could be hanging on two beams at a single point in the center. I'm also not sure if 2x6 cedar is hard/strong enough for this purpose.
In another area of the structure, I will be hanging boards across it like this:
Will an 8ft 2x6 cedar board be sufficient to support an adult?
