Why You Can't Lift People Like This In the YouTube video titled "Why You Can't Lift People Like This," presented by Kyle Hill, fans of physics and science fiction alike are treated to a deep dive into the impossibility of certain fictional scenarios—most notably, the famous "neck lift" seen in movies like
Star Wars. Hill explains that while it might seem superhumanly impressive to lift another person by the neck, the reality is rooted in human anatomy and physics.
Anatomy and Strength Limits
Hill begins by dissecting the human muscular system, noting that while we have around 650 skeletal muscles capable of great feats, the specific muscles involved in a neck lift—primarily the deltoids—aren't designed to support the kind of weight depicted in film. For instance, he estimates that even elite lifters can manage to lift only 60 to 110 pounds (27 to 50 kg) in a lateral arm raise, a far cry from the total body weight of most adults.
The Physics Behind the Lift
Next, Hill shifts into the realm of physics, explaining how
moments—the rotational forces around a pivot point—come into play. The challenge of lifting a person by the neck involves more than just muscle strength; it requires a delicate balance of forces. Due to the laws of physics, if a weight is lifted past a lifter's feet, it creates a substantial topping force that even the mightiest heroes couldn't manage. The moment created by the lifted person's weight far exceeds what can be countered by the lifter's shoulder muscles, resulting in a tipping effect.
Practicing Safe Lifting
Adding a practical twist, Hill encourages viewers to try a social experiment. He invites someone to attempt lifting them while standing close and then to gradually increase distance, which demonstrates how moments can change based on body positioning. This fun experiment reveals basic physics in a way that provokes thought and engagement—perfect for a community interested in science and tech.
Closing Thoughts
Ultimately, Hill reminds viewers that while the traditional neck lift as seen in films is impossible, certain adaptations and teamwork can achieve similar results in real life. The video is a perfect mix of humor, education, and myth-busting that arguably reflects the ongoing fascination with superhero lore and the underlying science that challenges it.
