Is wood stronger than steel and concrete?

Wood is stronger for it's weight than steel and definitely than concrete. Concrete has almost no strength in the tensile direction ( (being pulled) and relies totally on steel rebar for that strength.
Wood is stronger than steel and is fatigue resistant, where you can flex it a lot and it doesn't get weaker and break. But wood has to be oriented correctly for it's strength qualities to be utilized and has to be protected from the environment (so does steel)
Steel is unique in that it can welded easily and doesn't split and can be extruded to whatever shape and length is needed, so it is easy to fabricate and make structures.
But for pure strength for it's weight, wood is stronger than steel.
Also the strands of fiber in wood make it almost impossible to tear even if the beam is loaded off center whereas steel has to be engineered so that loads aren't off center or a small tear in the outer skin can make the whole beam tear instantly.
Similar to trying to tear a piece of plastic from the edge which is very difficult, but if you put a 1/8" tear in that edge, the plastic tears with no effort. A steel beam does the same thing. A wood beam would not

It depends on the application. Have you seen a nuclear attack sub made from wood? There are not many tall buildings with wooden foundations. Would you trust a major bridge with wooden abutments?
