This spectacular video was waiting for my attack on golf carts until I failed. It's a YouTube video with Destin Sandlin with YouTubers (every day interesting) and with Mark Robbur. How badly is a golf ball a favorite of Dustin and Mark in the video? How hard is it? You are Can the best golf superstar ever hit it? They wanted to find out the blow they could not hit. SPOILER ALERT – They destroyed the golf ball.
But here's the cool part. If a ball is attacked like an ordinary man, he is being pushed on to the golf club clay. In this compression, the ball acts as a good spring. Yes, it is compressed for a very short time, but will return to its original location. This is called elastic compression. All spring of introducing physics is this type of elastic pressure (or extention) (often). In fact, Hooke's law is said to be all about. The example of the force exercised by the Spring, which states that the spring power is proportional to the compression or the protracted size, is the case. This seems to be an equation:
In this publication Fit The power exercised by the spring, it Compression size, and Million Spring constant – spring temperature measurement. In this equation, you are often regarded. It mentions that some people are in the opposite direction. But explain to me. Everything is not followed by Hooke's law. It's not really a law, but a guideline (actually not a scientific model). An object and object may have certain conditions No There must be a linear connection between power and the long.
But if you press heavier than a golf ball, it does not return to its original state. Rather, it breaks down as it is distorted. It's still spring-like properties, but it's not like it's before. It is something different. This is called plastic deformation. For example, imagine that you have several clay. If you squeeze it, it will be deformed in the new shape. It's not the same before you squeeze it.
In fact, an object may be elastic and plastic. The classic example is common paper. Take one and take it out as it looks.
In this video, ElaStick in the form of a paper-based scanned plot of paper.
This is a beautiful sight that shows the main point. If you slip to slip paper slip, it will move to the elastic area. This means that when you are removed from power, the same starting point will not come back. It will change. Every article migrates to a plastic place somewhere. But is this really a graph in real life? Yes. That's what I'm doing. I even go to use paper.
It appears initially, but it must be a trick. They are fixed to the paper using a certain device. The other side of the paper is attached to a fortress and a wheel motion sensor. The emission of power can clearly measure power. In fact, the displacement of the motion sensor is measured. By knowing the radius of the wheel, the angular position can be converted to the linear position. A combination of these two sensors will provide me with power. Here's what it looks like.
These data are very weak. Remember, this is a relative position relative to power – it does not appear. However, if you use your imagination, you can imagine what is happening. After a bit of squeezing, the same part of the conspiracy, which has been circled as a "round shape" of paper writing. Turning this data forward will proceed along that line. That's normal spring. But when you find it very difficult, it returns in another region with a different final place. Yes, it is distorted.
But the most important thing in this conspiracy is not the area under the curved elastic region (not blue in Dustin's illustration). The elastic division is a line.
If you find the slope of any part of this data, it will give a constant spring constant for the paper. The plastic slope region is similar to the elongated regional slope. Of course, these papers are still well-behaved (elastic), but with a different length.
Oh, what about traditional physics? You are kind of used in the physics laboratory. What happens when one of these weakens? Here is the place for spring, a similar conspiracy of power.
In this case the spring extended so much More than that paper. In fact, it is almost a meter away. It was then only in the plastic zone. Also, in the spring "behavior" is a bit easier to find spring constant. The fracture of the linear bumps is about 8.6 Newtons per meter, which is after partially destroyed. Of course, this is excellent. You know that physics students violate these fountains (of course not). But more and more, they still can adapt to Hooke's law.
What about the golf ball in a video by Dustin and Mark? Disappear. It's over. The remaining ball will even behave like a ball before it strikes it.
