Load Takes the Path of Least Resistance
When you put weight on a bridge, the force doesn't spread magically—it follows the structure.
Load distribution = how forces spread through a structure from the point of application to the supports.
Key concepts:
- Concentrated loads = dangerous (all force in one tiny spot)
- Distributed loads = safer (force spreads across larger area)
- Load follows structure (beams, cables, supports)
Think of it like water flowing: Water takes the easiest path downhill. Forces take the path of least resistance through the structure.
