It depends on the species of wood the joists are made from but it should be in the low 11 to mid 12 foot range. Note that the span is the distance between the inside edges of the end supports, so a 12' joist on 2x4 walls will actually span only 11'5" (12 - 3.5 -3.5)

Length of arc, with angle x is pi*r*x/180 (where r is the radius) = pi*16*20/180 = 5.59 inches.
The maximum allowable ceiling joist span for a residential building is typically around 16 to 24 feet, depending on the building codes and the size of the joists used.
The recommended spacing for deck floor joists is typically 16 inches on center.
The recommended spacing for floor joists in a residential construction project is typically 16 inches on center.
The recommended spacing for 2x6 floor joists in a residential construction project is typically 16 inches on center.
To find floor joists in your home, you can use a stud finder or look for nails or screws in the baseboards or ceiling. You can also measure 16 or 24 inches from a wall, as joists are typically spaced at these intervals. Another method is to locate a floor vent or electrical outlet, as they are often attached to joists.
To locate joists in a floor, you can use a stud finder or tap the floor to listen for a solid sound indicating the presence of a joist. You can also look for nails or screws in the baseboards or ceiling below, as they are often attached to the joists. Another method is to measure 16 or 24 inches from a known wall, as joists are typically spaced at these intervals.
To locate floor joists in a room, you can use a stud finder or measure from a known reference point, such as a wall. Floor joists are typically spaced 16 or 24 inches apart, so measuring from a wall at one of these intervals can help you find them. You can also look for nails or screws in the floorboards, as they are often placed along the joists.
About 5metres(16') but would have to be stress graded timber.
I don't understand your question completely, but I think what you are asking is how far apart support can be for a subfloor or floor decking. It will vary with the type of construction, but for residential housing it's almost always 16 inches between the floor joists. That would be measured from the center of the joist to the center of the next joist.
The thickness of subfloor needed generally depends on how far apart your floor joists are located. In most cases, floor joists are 16" center-to-center and the most common thickness of subfloor is 3/4". Some homes will have 1/2". If your floor joists are farther apart, you will need correspondingly thicker subfloor to adequately support weight between the wider joists. Your city's building codes department will be able to specify what you need (some cities may have differing requirements).Another factor might be the kind of flooring you will install. For carpet, vinyl, laminate, wood and other non-rigid flooring types, the 1/2" or 3/4" will be adequate. For tile, the Tile Institute of America recommends no less than 3/4" subfloor on 16" centers floor joists - but with 1/4" backerboard installed on top of subfloor. See their website or contact your city codes department for specifics on a different span of joists.
Reinforcing a floor that moves when someone heavy walks on it can be done by adding additional support beams or joists underneath the floor. You can also use bridging or blocking between the existing joists to add stability. It's important to identify the specific areas that are moving and target those for reinforcement.
The answer to this question depends upon several criteria: 1. The span of the floor framing members 2. The 'on center' spacing of the floor framing members 3. The nominal dimension of the floor framing members (2x12 etc.) 4. The grade and species of the wood 5. Size and location of any holes or notches in the framing members A typical residential floor designed for a 10 psf Dead Load, 40 psf Live Load and a deflection criteria of L/360 (mid span deflection limited to L in inches/360): 2x12 joists at 16" on center spacing, Spruce-Pine-Fir #2, will have an allowable max span of 17'-10". 2x12 joists at 16" on center spacing, Southern Pine #2, will have an allowable max span of 18'-10". 2x10 joists at 16" on center spacing, Spruce-Pine-Fir #2, will have an allowable max span of 15'-5". Random thoughts: Thinset ceramic tile with mortar will add about 10 psf dead laod. Location of very heavy objects can be critical when determining a floors capacity.
