Want this question answered?
three lbs
i say that the answer is 16 because 2x8 is the same thing as pint x 4 so it is 16
1x16, 2x8, 4x4
3
Conventionally, it would be 2 units wide.
three lbs
That would depend on the specie of wood that the 2x8 is made from.
how much weight will 5 2x8 that span 12 ft hold
A 2x8 refers to a 2 inch by 8 foot piece of wood. The span of a 2x8 is 8 feet.
Depends on the area above the ceiling joists. Is it a live load (living space) or dead load (just the joists with maybe an attic above)? Also, the length of the ceiling joists from the last bearing point is a factor. How much weight is bearing on the beam is the critical issue.
2.15
That depends on how well supported the floor is and that depends on how far apart the joists are placed. The closer they are, the more weight can be supported.
Could be a couple of different reasons.... Your ceiling joists could be longer than the recommended span for the size of the joist [ie: 2x6 or 2x8], and over time the weight of the ceiling material and whatever is directly above them may be bowing the ceiling down.... or In older homes with plaster ceilings with wood lath instead of gypsum sheet panels [sheetrock], the plaster sometimes breaks free from the wood lath and sags. This especially happens when there has been a water leak above the ceiling at some point......
The price for a 2x8 LVL is approximately 3.03 per foot while dimensional lumber 2x8's is selling for $0.80 per foot. So the answer to your question is no. Laminated veneer lumber is not cheaper than dimensional lumber.
17-(2x8)=1
what is the load bearing weight for a 2x6x10
2X8 set 16 inch on center.
