| When a strong wind isn’t blowing, a 2x4 with at least 8 feet vertically can hold at least 1000 pounds. Such calculations are valid when the load is square, for example. However, it is highly recommended not to push 2x4 material to its limits.
Finding a Nail A regular cast can’t hold more than a few pounds, but a thin nail in a needle can usually hold up to 20 pounds, and several coarse wood screws in wood studs can usually hold up to 20 pounds. up to 100 lbs or more.
Rocket says a 2x4 can handle 18,000 pounds of compression. Additionally, a 1x4 can handle half the load of a 2x4. So a vertically supported rack can support a vertical load of 45,000 pounds by purchasing 5 1x4. VEI weighs more than a fully loaded 156 gallon tank.
Fine Homebuilding notes that 2 x 6-inch garage joists can support up to 50 pounds per square foot. If you overload the garage roof joists, the roof could sink under the load. While 2 “by 6” beams can collapse due to excessive weight, such a scenario is rare.
It can be anywhere from 5 to 10 pounds, but keep in mind that drywall is an extremely brittle material and is not strong enough to support weight for long periods of time.
If it is an exterior wall, it is almost always load-bearing. If the joists are not continuous on the wall (they are sawn and meet at the top of the wall), they are definitely load-bearing. If there are only lights on a flat 2x4 to attach the patch to, it is likely not load bearing.
In the absence of strong winds, a 2x4 that is at least eight feet vertically can hold at least 1,000 lbs.

Weight restriction. Axial load or load weight limit for metal pins varies widely. For example, an 8ft 31/2-inch metal stand can support over 2,000 pounds while a 16-foot of the same width can only support 400 pounds.
Zach Eyman: A good rule of thumb is 80 lbs for a single bolt, but specific mounting specifications should always be followed. Eighty pounds and later is roughly less than 60 inches.
Span can carry 10 psf while a 2 × 8 can carry 20 psf. The two together result in a payload of 30 psf.
So the area between two 2x6.6 long, with 2 intervals, 2x6x40 = 480kg must support the weight. Actually a little more, because the formula applies to 86 spans, but this only gives you a small advantage in terms of safety.
How to hang very heavy objects from the ceiling
Unless you have a flat roof, trusses and suspended beams are provided to support the roof only. You can not withstand a load on the sloping roof, this is the task of the cantilever beams.
In fact, each 2x10 supports 1200 lbs.
If you are unsure whether the roof, rafters or rafters can carry the heavy bag, it is best to hang a punching bag with a wall bracket in the garage. You can find wall brackets at any hardware store or sporting goods store. Then screw the bracket to a wall bracket in the wall near the ceiling.
Find a ceiling beam of at least 2 x 15 cm in the desired position so that it can support the weight of the chair and the person sitting on it. If your porch roof is covered, you can use a post detector to locate a beam, usually horizontal roof supports. This is where the chair comes in.
2 and better (no loose or missing buttonholes), so a 4x6 stretch 18 can carry around 105kg.
