16 14′ – 5″
24 12′ – 4″

How much weight will a 2×8 support?

some of it gets pretty technical in nature, and mostly relates to pounds / square foot of loading. 2x6s are generally used for ceiling joists, esp since you said 24″ oc and reallllly short spans only (5 or 6 feet ). Most floor loads would be a minimum of 2×8 @ 16″ oc and most preferbaly 2×10.

10′ feet

How much weight can a 2×4 stud support?

How far can you cantilever a 2×8?

Granted 4x4s when used vertically are still rather strong for most applications, but should never be used horizontally for something structural. Also remember and remind yourself (repeatedly, if need be ) that two 2×4 is NOT dimensionally the same as a 4×4. In this case, two 2x does NOT equal a 4x.

How far can you cantilever a 2×8?

Find a Stud

A nail in just drywall can‘t hold more than a few pounds of weight, but a thin nail in a wood stud can typically hold up to 20 pounds and several coarse threaded wood screws in wood studs can typically hold up to 100 pounds or more.

What is the maximum span of a 2×6 floor joist?

Max. Live Load 30 lbs/ft2 (1436 N/m2)

Can I use 2×4 for floor joists?

before being supported by a girder – then yeah, a 2×4 should be okay. 2×4 are suitable for ceiling joists where the LL is like 20 Lbs. If you got a good species with the highest Modulus of Elasticity and Best grade and use like 12″ o.c. – you might get 8” span.

How do you determine the beam size on a load bearing wall?

The formula for the section modulus is beam width times beam depth squared divided by 6. A two 2-by-6 standard beam has actual dimensions of 1.5-by-5.5 inches which would give a section modulus of 1.5 x 5.5 x 5.5 / 6 = 7.6 which is not enough for this example. A 2-by-8 beam would be sufficient.

How do you determine the beam size on a load bearing wall?
