# How strong is 2x4?

**2x4**carrying a uniform load of 40 pounds per foot (400 lbs total load) will have a maximum bending moment at the center of the span of 1000 ft-lbs. The same 10 foot long

**2x4**with a point load of 400 lbs at the center will experience a maximum bending moment of 500 ft-lbs.

In this regard, how much weight can a 2x4 hold?

Assuming that the load is square and there is no wind, the average 8 feet **2x4** could handle around 1,000 pounds vertically. Of course, it's wise not to push the material up to its limit, use brace and alike to secure the 2x4s whenever it's needed.

Subsequently, question is, how much force does it take to break a 2x4? It would probably take over a thousand pounds to **break a 2x4** in half on its short length.

Beside this, are 2 2x4 as strong as a 4x4?

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 2x4** is NOT dimensionally the same as a **4x4**. In this case, **two** 2x does NOT equal a 4x.

How far can you span a 2x4 ceiling joist?

The **ceiling joists** are 2X4s on 16 inch centers that **span** the 10 plus feet.
