Consequences of Removing a Load-Bearing Wall

What happens here

The presenter demonstrates the importance of a load-bearing wall by removing the central interior load-bearing wall from the model using a screwdriver. As the wall is removed, the roof structure visibly sags, and the ceiling collapses, illustrating that the spliced rafters cannot handle the increased span without the central support. In contrast, a non-load-bearing wall perpendicular to the removed wall remains unaffected, showing its lack of structural importance.

Goal: Visually understand the structural failure caused by removing a load-bearing wall.
