Impact force?
Idk if what I’m asking makes sense but I’ll do my best to explain my thinking. I work in a shop that keeps its loading dock doors open in the summer. The drop off is 3 feet 8 inches. Safety regulations require a temporary barrier (like a chain) to be present for drop offs of 4 feet or higher. Obviously being 4 inches below the minimum height doesn’t make it incredibly safer. How can I calculate the impact force from both heights? I’m just doing my best to advocate for a safer work environment for my coworkers and want the facts on my side
