How much weight can a 2x6 support horizontally. The sagulator says borderline sag began at about 12500 pounds but that was beyond their stated target sag of 002 ft. How much weight can a 2x6 hold on edge based on load type. So the plank is a total of 7 feet long. On the other end a 2x6 can support a v8 engine of between 600 700 lbs.
How much weight can a 2x4 support horizontally. The posts are spaced 3 feet apart. For commonly available types of wood eg. The weight that a 44 beam can support horizontally depends on the type and quality of the wood used.
For an example a 10 feet long 2x4 with a 40 pounds uniform load would have a maximum bending moment of 1000 feet pound. So the other guy saying a 2x6 is stronger than the 4x4 is right on. Putting those numbers into the sagulator a 12 2x12 ponderosa pine board lying flat could support 100 125 lbs with about 02 of sag in the middle. The plank is attached to each post with 2 boltsnuts on each post.
2x6 is more rigid under equal load id say your best bet would be to gang 4 2x6 together to use as beams under the load. The plank is located 8 feet high on the posts from the ground. 2x6 on edge 6 high 6 squared 36. People who want to know how much weight can a 44 beam support be it on the backyard swing set or the deck with a hot tub in it worry not because we have got the answers for you.
Learn how much weight can a 2x4 support. How can i calculate the maximum load a rectangular horizontal wooden beam of dimensions l x h x w can safely support if the beam is adequately supported at both ends. Actually slightly more since the formula is for 8 6 spans but it just gives you a little bit of extra load for just in case. The type of load in question will also determine how much weight a 2x6 can hold on edgefor example a 2x4 lumber may hold a 4 cylinder engine comfortably but may not hold a bigger one.
Assuming worst case load concentrated at center. The plank extends four feet from the 2nd post. So the area between two 2x6 6 long on 2 intervals would have to be able to support 2x6x40480 pounds of weight. Search is the most efficient way to navigate the engineering toolbox.
If it were on edge it could support several thousand pounds. In this case we have to take into the load position is it a uniform load or only a point load.
