Trees, regardless of size, all break at the same wind speed. Here’s why.

When a cyclone named Klaus tore across southwestern France in January 2009, it highlighted a
strange phenomenon: Trees, regardless of their diameter, height, or elastic properties, don’t tend to break until wind speeds reach about 42 m/s (94 mph). This seemingly odd convergence has actually been observed by several historical scientists, including Galileo and Leonardo da Vinci, both of whom suggested that a mathematical law could explain the resistance of wooden beams under stress. Now, using data from a new experiment, scientists say they have found that law.
