How much weight can a double 2×8 support?
For a 2 x 8 joist and a double layer of 3/4″ something (plywood/osb; a single layer will probably be too thin to support heavy equipment) you’re looking at something on the order of 15 pounds per square foot (psf) minimum for joists at 16″ centers.

How far can a double 2×8 floor joist span?
2 Answers. No, you cannot span 23 feet with conventional lumber, even doubled. It’ll be as bouncy as a trampoline and won’t meet code, and that’s if you can find such lengths. You’ll need at least a 12″ (nominal) I-joist or an engineered floor truss to span that far, or you’ll need an LVL or steel beam midway.

How far can a 2×6 Rafter span without support?

Are two 2×6 stronger than a 2×8?
Kaiden;as Daniel said, the two 2×6’s will be slightly stronger than one 2×8. (I think by around 10%). However, whether or not they will work for your situation depends on the loading stipulation and deflection limits for your floor, which presumably is in your Code.
Is a 4×6 stronger than 2 2×6?
A 4×6 joist is theoretically stronger than a doubled 2×6 joist because it’s 1/2″ thicker, but the actual strength depends upon the knots and other inherent weaknesses of any particular piece of lumber (#2 lumber can have some nasty spike knots or large not-so-tight round knots or wane).
