Grabbing something at Terminal Velocity

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of surviving a fall at terminal velocity while attempting to grab onto a horizontal pole. Participants explore the physical consequences of such an action, considering various scenarios and the forces involved.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions whether grabbing a cantilever pole at terminal velocity would result in severe injury, such as dislocated arms or worse.
  • Another participant suggests that falls at terminal velocity are typically survivable only when landing on forgiving surfaces, indicating that abrupt stops are likely fatal.
  • A different viewpoint emphasizes the improbability of surviving a fall while grabbing a solid object, noting that the force exerted could easily dislocate shoulders or cause other injuries.
  • One participant reflects on the unrealistic portrayal of such scenarios in movies, suggesting that the physical consequences depicted are often exaggerated or implausible.

Areas of Agreement / Disagreement

Participants express differing views on the survivability of falls at terminal velocity when interacting with solid objects. There is no consensus on the outcomes of such scenarios, with some emphasizing the fatal nature of abrupt stops and others considering the mechanics of grabbing onto a pole.

Contextual Notes

Participants do not fully explore the mathematical implications of the forces involved, nor do they clarify the assumptions regarding the strength of human limbs or the properties of the pole.

I know in Hollywood people fall a couple stories and grab onto a pole or something and survive, which most of the time doesn't seem too far fetched. But what if you were falling at terminal velocity and grabbed onto a horizontal pole? (The pole being a cantilever, and not flexible or anything at all, like a real world scenario)

Suppose if you grabbed onto it with both arms, would the force just rip your arms off, or just dislocate your arms and actually survive it?

What if you caught it between your chest, and wrapped your arms around it, parallel to the bar. I assume the force would still be fatal, and cause more damage since all the force will be undistributed. Would it be like grabbing a sword or something and just rip right through you or would you actually survive it.

If neither of these ways are possible, is there a way to survive without the pole being flexible?

The only falls people survive at terminal velocity are into something that gives quite a bit. Dense bushes, deep snow, that sort of thing. Anything that stops any part of your body more or less instantly is sure to be fatal.

Actually, it does if you think about it. The force of an adult male weighing, say 180lbs falling 3 stories and grabbing a solid railing is certainly enough to dislocate his shoulder even if he could manage to hang on, which I think is likely impossible since hands aren't that strong.

The damage that the heroes sustain, and more or less casually walk away from, in movies is usually completely ridiculous.
 
Wow, haha. Never thought about this topic before but is certainly very intriguing.

One of my assignments in high school physics class was to watch a movie and note all of the "physics is broken" moments. Haha.
