30 kg is about the same as 600 kg.
For a simple example, the maximum length of X 10 used by the national team is 380 deflection, and C 1 is the hardest. If it is 300, you need to cut off about 1.2 inch, which is almost about 29.5. If it is a tungsten steel head. Because the original arrow is about 1 inch long, it needs to be shortened a little.
Generally, men's teams can use this, almost 44 kg upward. Actually, more than 48 kg will use such a hard arrow.
Deflection corresponds to the softness of the arrow, which is also the reason why high weight and low deflection will directly explode the arrow. The bow exerts too much force on the arrow, which leads to the bending degree of the head and tail exceeding the bending limit of the arrow material. Reasonable deflection can effectively control the bending within the range, but excessive deflection will lead to the bending of the arrow except the ejection, because the instantaneous acceleration will bend it. After rebounding, the high deflection of the arrow will make the arrow shake quickly and never, but the first bending has made the arrow deviate from the axis of the bow target, and it can't come back without the subsequent compensation jitter. The basic result is either off target or off target. For competitive rebound, it is even more serious, because competitive rebound also has a side pad to reduce jitter. If the side pad is adjusted according to the number of pounds (there is no doubt that a long-term shooter can know whether the side pad is suitable by pressing it with his hand), then the rebound of the arrow will seriously consume the life and quality of the side pad spring. If you adjust according to the deflection, congratulations, all the arrows have bounced off.
Deflection and pounds are completely opposite. The smaller the number of pounds, the greater the deflection value. For a 30-Jin bow, if it does not exceed the allowable pulling distance (64-inch bow 24-inch, 66-inch bow 26-inch, 68-inch bow 28-inch, 70-inch bow 30-inch, 72-inch bow 32-inch), almost 1000 is enough, and you can buy 900 for safety.
Don't worry about buying a bow Just watch some popular science videos of the International Arrow Federation. Go to the arrow hall and find a coach to practice. Even if I did, I wouldn't ask this question.
A compound bow with a heavy arrow will do. .
It's not the bow that wears out the arrow.
It was the arrow that frayed the bow.
It is also possible that both of them are broken.
This arrow is too hard. If the competition is reversed, try 900 or 1000.
See what kind of bow and arrow it is. If you have a 30-pound compound bow, a 300-turn shaft and a very heavy arrow (over 300 grains) may also be appropriate. But even so, the arrow is easy to be overweight. The mismatch of arrow deflection has an impact on accuracy, that is, it can be corrected with a large arrow feather, but the fault tolerance will be very low. In addition, as mentioned above, because the arrow is too hard. There will be a lot of friction between the cone and the shaft, which is easy to wear.
The arrow is too hard, just go through the platform or out of the point. The key is to touch when you go out. How do you know where the arrow will tilt?
One question that most answers don't mention is the length of your arrow. The so-called deflection is the curvature of the arrow shaft obtained by the arrow shaft manufacturer hanging heavy objects at a fixed length of 28 inches. The longer the shaft, the lower the actual hardness of the shaft. For example, an arrow shaft deflected by 30 inches at 660 is as hard as an arrow shaft deflected by 29 inches at 730.
The choice of arrow length is flexible, but it will not be shorter than your drawing distance at first. If competitive recurve bow wants to put the clicker on the bow handle, the length of the arrow shaft is generally one inch longer than the distance of pulling the bow.
Above.
If you don't aim at a particularly accurate lens, of course, the harder the better. After all, low deflection means that the arrow is straight when it is shot and will not bend when it hits the target. Almost all kinetic energy is transferred to the target, and its lethality is also great.
Normal 30 pounds is suitable for 500-700 torque.
Low deflection will make the arrow unable to bypass the bow handle through enough bow potential energy after it exits, so the arrow branch will be biased to the side of the arrow.
The arrow will swing sideways when it flies. As for whether it is level when hitting the target, it depends on luck. Anyway, it will swing sideways with the naked eye.
The target on the arrow should not be straight, and the flying arrow may be slightly disguised in the air. Excuse me, 30 Jin. 500 yuan feels quite suitable.
It's too difficult to shave 300. The arrow flies obliquely when it goes out and obliquely when it hits the target. Is it accurate? It will be much better to use about 800 for 30 kg.
Not good at all. It doesn't match at all. How to adjust it?
no problem
If you spill the beans, the main problem is to expose the fact that you don't know anything, which will make you lose face.
It's not straight. I think it's almost done with 700.
