Vi en Internet que los internautas mencionaron el problema del equilibrio de yubai. Algunas personas dicen que después de envolver el pegamento novato, el punto de equilibrio de la raqueta se mueve hacia atrás; Personalmente, creo que es un malentendido del punto de equilibrio.

I saw on the Internet that netizens mentioned the problem of the balance point of Yubai. Some people say that the balance point of the racket is moved backward after the novice glue is wrapped; Personally, I think this is a misunderstanding of the balance point.
First of all, the balance point is just a parameter used to indicate whether the racket is head-heavy or head-light. Tong Yang is a 3u racket. Why do some rackets feel more difficult to swing and more powerful to smash the ball; some rackets are easier to swing and return faster. This is why the weight of the racket is concentrated in the head or not.
But balance is not an ability
An indicator that reflects the actual weight of the racket head. After the racket is bought, it will be put on the string and wrapped with hand glue. At this time, the balance point has changed. But this will not substantially change the weight of the racket head.
Whether the head of the racket is light or heavy is actually determined after the production process is completed. The Ti-10 2U old color is a well-known head-heavy racket. Just imagine, will this racket become a light-headed racket because of the addition of hand glue? Read the explanation below and think about it.
Everyone should have a certain concept of leverage mechanics. In the principle of leverage, there are load point, heavy arm, fulcrum, moment arm, and force application point. When swinging a racket, the "load point" is on the racket head, the "fulcrum" is on the thumb (not the balance point), and the "power point" is below the thumb. The weight we feel when we swing the racket is the weight extending from the fulcrum (the place where the thumb is pressed) to the head of the racket; while the weight of the handle and hand glue falls on the moment arm between the fulcrum (thumb) and the point of application In fact, the weight of this section will not cause the load when swinging the racket. Therefore, wrapping the hand glue will not constitute a physical transformation such as "the weight of the racket head is reduced". The balance point parameters provided by the factory are just reference values. The addition of hand glue does move the balance point of the racket to the handle, but the actual weight of the racket head does not go away.
Ok, back to the question just now: Will the old color of the Ti-10 2U become a light racket because of the addition of hand glue? The answer is no, its performance is still the top-heavy racket.
We use the user to test the balance point by placing the racket shaft on a finger and moving it left and right to reach a balanced state. The position where the finger supports the racket shaft is the so-called "balance point of the racket". This is also a form of leverage, but it is not the leverage we have when we swing.
The balance point obtained by doing this balance point test is not a correct way to measure the actual weight of the racket head. We can only use this method to compare two racquets, which one has a heavier head in the same condition.
For example, a 3u Arc-7 and a 3u MP99, both rackets are in the state of the empty racket and the original hand glue, you can use the above test method, the result will find that the balance point of the Arc-7 is closer to the As for the handle, the balance point of MP99 is closer to the racket head. So we know that the head of MP99 is heavier than Arc-7.
If one of the racquets is wrapped with extra hand glue, then before testing, the other racquet should be wrapped with the same weight of hand glue. This is a correct test method. If it is the same racket, it is a wrong way to compare the balance point after lagging and before lagging. As for the method of adding or subtracting counterweight to the handle to adjust the balance point, it is also a fallacy.
As mentioned above, the weight you feel when you swing comes from the head and shaft, not the handle. That is to say, any addition or subtraction of counterweight on the handle will not constitute a change in the actual weight of the racket head. This only causes the racket head to be lighter or heavier relative to the handle, and the change of this relative relationship will not change the feel of playing.
