Description
Can you fix a sagging floor joist simply by flipping it upside down and letting gravity work in reverse? It sounds like a quick and clever solution, but structural lumber physics tells a very different story.
In this video, we break down why flipping a deformed floor joist is a dangerous shortcut. Over time, wood subjected to continuous loads undergoes permanent deformation. The top fibers become permanently crushed under compression, while the bottom fibers are stretched out under tension.
