really depends on different situations your trying to have... considerations of various stresses and forces, including supports, reactions and the behavior of every materials (the wood and the supports) regarding the applied weight or force...very broad question. using different kinds of wood, may already yeild different answers..

Are we talking a 2x4 standing or laying down? If standing the problem will be explained by Euler's rules for buckling loads. If laying down wood can handle a lot of load. Wood is not a homogenous material, so the actual numbers would depend on the structure of that specific 2x4.

Two answers.
A lot. The compressive strength of wood is enormous. Structures are basically designed to load wood in compression. Bending strength is far less.
The speciific answer obviously depends on how long the 2X4 is.

don't forget! there are many different grades of 2x4s!
