Exploring the Effects of Near-Light Speed Rotation on a Pole

In summary, the conversation was about a crane spinning and the potential effects of an extremely long, rigid pole spinning at high velocities. However, it was pointed out that such a pole does not exist and the question has been asked before. The consensus was that the pole would break at high velocities.

Ok. I got this today from looking at a crane spinning around.

What if you had an extremely long pole, huge order of magnitude, and you spin it. As you go outward, the velocity of the particles of the pole increase. As this velocity nears c, what happens to the pole as you keep going further away from the origin of rotation?

Doesn't work. There is no such thing as a pole that is as rigid as you are thinking of. This question in one form or another is asked here every few months. Do a forum search for "rigid body"

What Phinds said. Also, there's an entry in the FAQ at the top of this forum: https://www.physicsforums.com/showthread.php?t=536289

Ha, wow, can you say oblivious. Thanks phinds and Nugatory.
 

1. What is near-light speed rotation?

Near-light speed rotation refers to an object, such as a pole, rotating at a speed close to the speed of light. This means that the object is rotating at a very high velocity, which can have significant effects on its physical properties.

2. What is the purpose of exploring the effects of near-light speed rotation on a pole?

The purpose of exploring the effects of near-light speed rotation on a pole is to better understand the behavior of objects rotating at extreme speeds, and how it affects their structure and properties. This research can have implications in various fields such as physics, engineering, and space exploration.

3. What are some potential effects of near-light speed rotation on a pole?

Some potential effects of near-light speed rotation on a pole include changes in its shape, density, and mass. It can also cause time dilation, in which time appears to pass slower for the rotating object compared to a stationary observer. Additionally, the pole may experience increased stress and strain due to the high centrifugal forces.

4. How is near-light speed rotation on a pole studied?

Near-light speed rotation on a pole can be studied through simulations and experiments. Simulations involve using mathematical models and computer simulations to predict the behavior of the rotating pole. Experiments can involve building rotating poles and measuring their physical properties at different speeds.

5. What are some potential applications of the findings from studying near-light speed rotation on a pole?

The findings from studying near-light speed rotation on a pole can have various applications in technology and space exploration. It can help improve our understanding of the behavior of rotating objects, which can be useful in designing faster and more efficient machines. It can also provide insights into the effects of extreme speeds on objects, which can be relevant for space travel and exploration of other planets.
