I saw netizens on the Internet mention the problem of the balance point of the feather racket. Some people say that after wrapping the new glue, the balance point of the racket moves back; Some people say that it is necessary to add or subtract counterweights from the handle to adjust the balance point. Personally, I think this is all a misunderstanding of the balance point.

First of all, the balance point is simply a parameter that indicates whether the racket is biased towards heavy or light heads. Same as Yang is a 3U racket, why some rackets feel more difficult to swing, killing the ball is more powerful; Some rackets swing more easily and return faster. This is why the weight of the racket is concentrated on the head or not.

But the balance point is not a can

An indicator of the actual weight of the pat head. After buying the racket, it will put on the ball line and wrap the hand glue, at which point the balance point changes. But this does not materially change the weight of the pat head.

Whether the racket head is light or heavy is actually determined after the production process is completed. Ti-10 2U The old color is the famous head heavy racket, just think, will this racket become a light racket because of the addition of hand glue? Let's take a look at the explanation below and think again.

Everyone should have a certain concept of lever mechanics. In the principle of lever, there are negative focus, heavy arm, fulcrum, force arm, and force point. When swinging the racket, the "negative focus" is on the head, the "fulcrum" is on the thumb (not the balance point), and the "force point" is below the thumb. The weight we feel when we swing the racket extends from the fulcrum (where the thumb presses) to the section of the head; The weight of the handle and glue falls on the arm between the fulcrum (thumb) and the force point, and the weight of this section does not cause the weight of the swing. Therefore, wrapping hand glue does not constitute a physical change such as "the weight of the pat head is reduced". The equilibrium point parameters provided by the factory are only reference values. The addition of hand glue did move the balance point of the racket towards the handle, but the actual weight of the head did not go away.

Well, 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, it still performs as a heavy-headed-heavy racket.

We use the user to test the balance point, which is to put the racket lever on one finger, move it left and right to the balance state, and the position where the finger supports the racket is the so-called "balance point of the racket". This is also a form of leverage, but it is not a lever when we swing the beat.

The balance point obtained by doing this balance point test is not a correct way to measure the actual weight of the pat head. We can only use this method to compare two rackets, which one has a heavier head in the same state.

For example, a 3u Arc-7 and a 3u MP99, both rackets are in the state of empty rackets and original hand glue, you can use the above test method, the results will find that the balance point of Arc-7 is closer to the handle, and the balance point of MP99 is closer to the pat head. This way we know that the MP99's head is heavier than the Arc-7.

If one of the sticks is extra wrapped with hand glue, then the other hand should also be wrapped with the same weight of hand glue before doing the test, which is the correct test method. If it is the same racket, it is a wrong practice to compare the balance point after coating and before coating. As for , the practice of adding or subtracting counterweights on the handle to adjust the balance point is also a fallacy.

As mentioned above, the weight felt when swinging comes from the head and rod, not the handle. This means that any addition or subtraction of counterweights on the handle will not constitute a change in the actual weight of the pat head. This only causes the head to be lighter or heavier relative to the handle , and this relative change does not change the feel of the ball.
