What happens here

After both pieces of lumber have been tested, the presenter holds up the two broken 2x4s side-by-side to visually compare their failure characteristics. He explicitly states the results: the lumber with pith ('Pith') broke at 10,000 pounds of pressure, while the plain lumber ('Plain') broke at a significantly higher 16,000 pounds. He reiterates the importance of these findings, advising DIYers to carefully check the grain of lumber, especially when selecting materials for critical structural components like rafters and joists, to ensure they are free of pith for maximum strength and durability.

Goal: Understand the practical implications of pith in lumber for structural applications and make informed choices.
