The study looked at how strong wood is when pulled in different directions. They tested Sugar Maple wood samples to see how well they held up when pulled radially, tangentially, and at a 45-degree angle. The researchers found that the strength of the wood varied depending on the direction it was pulled in. Radial and tangential pulls showed significant differences in strength, while the 45-degree pull was different from both. This information is important for understanding how wood behaves in different situations, like when it shrinks or when beams made of wood fail.
