I'd like to know how much weight a 4X6, 4X8, and 4X10 wood beam can carry over a 15 foot span. The weight would be evenly distributed.

Engineering advice from an internet site like this with no other information about the design of the house is worth what you pay for it.

A fifteen foot sapn is likely to require a man-made LVL or glulam. You give no details about what it will support. Roof only?
or just taking the bounce out of some floor joists midspan with no actaul loading?
header for three stories above?

Complete plans are necessary for complete answer but a generic rule of themb would call for this beam in fir to be a 4 x 18 or 4 x 16

I brought a coop and the kitchen floor is sloping! What can be causing this? My neighbor has a ceramic floor applied over thinset concrete.Our kitchens are back to back.Could this be causing the sloping or a poor design when building the coop be the problem?

Hello:
Looking at building an 14'×14' deck for a Hot Tub thst will be 8'×8' for 6 to 8 people. The lumber i will be using will come from Home Depot or Lowe's " Pressure Treated Wood", Question is: Would 4×6×12 @ 16" on center support the Hot Tub weight witch may be about 102 lbs to 105 lbs per square foot?
Foundation will be on a 12"×8"×8" deck block set into a 18"×18"×4"" base for foundation support.
