Which wood is most bendable?
Softer woods are easier to bend, so pine, fir, and spruce are prime choices. Straight, vertical grain is far better for bending boards than wood with visible rings or C-shaped patterns in its end grain. Avoid knots as they rarely bend and are the most likely location for snapping wood while bending.
What is bendable wood called?

What does flexibility mean in wood?
By flexibility I mean e.g. how much will a shelf of a given thickness and grain orientation bend when a load is placed on it. I don't really care about max load or breaking point, just a way to compare wood types of the same thickness under the same load.
How to measure stiffness of a material?
In reality, the stiffness of a material is measured by the product of E and I. Consider the image below, taken from the AISC Steel Construction Manual, 7th Edition. The equation for delta (deflection) is a function of 1/ EI. As the stiffness increases (product of EI gets larger), deflection decreases.

What is the right type of wood for construction?
In order to find the right type of wood for every construction project, builders refer to the strength of a wood. Different woods, classified into hardwoods and softwoods, are good for different types of projects. Wood strength is not given in a single measurement.
How is wood hardness measured?
Hardness is the measure of wood’s ability to resist denting and scratching. The lumber industry rates a wood’s hardness using the Janka hardness scale, which measures how many pounds of force (lbf) it takes to drive a 0.444 inch steel ball halfway into the wood’s face grain. The more force it takes to drive the ball into the wood, the harder the wood, and the higher the Janka rating. Common red oak has a Janka hardness of 1220 lbf, meaning it takes 1220 pounds of force to drive the steel ball halfway into the wood. For reference, soft balsa wood requires only 67 lbf and the hardest wood in the world, Australian Buloke, has a Janka hardness of 5060 lbf.

What is the purpose of wood hardness?
You can also use a wood’s hardness to determine its relative strength compared to other woods. Hardness is an especially useful measure of a wood’s suitability for flooring. A wood’s strength isn’t static, however. It varies with the direction of the wood grain.
How is wood strength expressed?
It is expressed using a number of measures, such as its density (the weight per a given volume); its compressive strength (or how great a weight a load of wood can bear parallel to the grain before it ruptures); its bending strength (a load of wood perpendicular to the grain); and its hardness. The strength of wood fiber is very consistent ...

What is pin oak?
A particular species of oak, known as pin oak, produces trees that grow very straight and tall, like pines. Thus the heartwood is very smooth and straight-grained, and extremely strong, when made into the pegs or pins used for construction where beams are held together by pins driven through bored holes. Pin-oak pins are virtually impossible to break after installation, and they do not wear out even after hundreds of years of a building flexing in the wind.

What is the world woods poster?
The poster, Worldwide Woods, Ranked by Hardness, should be required reading for anyone enrolled in the school of wood nerdery. I have amassed over 500 wood species on a single poster, arranged into eight major geographic regions, with each wood sorted and ranked according to its Janka hardness. Each wood has been meticulously documented and photographed, listed with its Janka hardness value (in lbf) and geographic and global hardness rankings. Consider this: the venerable Red Oak (Quercus rubra) sits at only #33 in North America and #278 worldwide for hardness! Aspiring wood nerds be advised: your syllabus may be calling for Worldwide Woods as part of your next assignment!
