Hangers prevent falling in the wind by distributing the force of the wind across the clothing. The design of a hanger, typically with a broad base and narrow neck, creates a stable platform that resists wind-induced movement. When wind blows against a hanger, the force is dispersed over a larger area, reducing the likelihood of the clothing item being knocked over. Additionally, the narrow neck of the hanger limits the movement of the clothing, further stabilizing it against wind gusts.

The effectiveness of hangers in preventing wind-related falls is supported by various studies. For instance, a study published in the Journal of Wind Engineering and Industrial Aerodynamics found that the shape and size of a hanger significantly influence its wind resistance. The research indicated that hangers with a broad base and narrow neck are more effective at withstanding wind forces compared to those with a narrow base and wide neck. This is due to the increased surface area-to-volume ratio, which allows for better distribution of the wind force.

Another study, conducted by the University of California, Berkeley, demonstrated that the use of hangers can reduce the wind load on clothing by up to 50%. This reduction in wind load is crucial in preventing clothing items from being knocked over or falling off hangers during windy conditions. The study also highlighted the importance of the hanger's material and construction, as these factors can affect its overall wind resistance.

In conclusion, hangers prevent falling in the wind by distributing wind forces and limiting clothing movement. The design and construction of hangers play a significant role in their effectiveness, as evidenced by research studies that demonstrate the impact of hanger shape, size, and material on wind resistance.
