Because the general basketball court is 28 meters long, 15 meters wide, and the area is 420 square meters, and the backboard is thick (3 cm), the width is meters, the vertical height is meters, and the lower edge is meters from the ground. The inner diameter of the hoop is m (45 cm), painted orange, and the top surface of the hoop is horizontal, m from the floor, and the distance from the two vertical sides of the basket is equal. The nets are knotted with white string and hung from the hoops; It should be structured in such a way that there is a temporary pause when the ball passes through the basket.
The length of the net is not shorter than meters (40 cm) and not longer than meters (45 cm).
In this case, it is more reasonable, the distance of the basket from the ground should be from the overview of the court and for our height, the international men's basketball rules are the basket from the ground meters. In the NBA it's meters.

It's just right, it's not too high, it's not too low.

The height design of the basketball hoop is designed based on various factors such as human height and bounce ability, and a large amount of data is collected. The height of the basket from the ground is ten feet, which is the meter when converted to SI meters.
The man who first invented basketball was James Naismith in the United States. At first, the basketball hoop was just a simple hoop, Naismith fixed it to the stands at both ends of the indoor sports room, three meters above the ground, replaced the initial rebounds with barbed wire, and he also adopted the characteristics of football, football, hockey and other ball games to formulate the original basketball game rules.
Later, with the continuous improvement of people's basketball game rules and venue facilities, people removed the bottom of the basket from the prototype of the basketball hoop, that is, the basket, and replaced the peach basket with a wire ring, and replaced the original wire net with a wooden board to make a rebound, so that the basketball hoop was more perfect. In addition, Naismith improved the rules of basketball and established rules that do not allow running with the ball, pushing people, hitting people, etc.

Naismith, who invented basketball, prescribed it, and he used the unit of feet at the time, set it at 10 feet - an integer, but converted to meters - that is, three meters and five, the vertical height of the basketball hoop is meters, usually higher than the height of a person, but a person can shoot a ball when he jumps; If the height of the basketball hoop is reduced, the basketball will be easy to put in, and the basketball game will be boring; And if the height of the basketball hoop is raised, it will be too difficult for people to shoot, and there will be fewer people participating in the game.
It is precisely because of the height of the basketball hoop that a person can put in the ball by jumping hard that there are so many people who are passionate about the game of basketball. Modern basketball competitions and various forms of basketball games, the basic activities are around the high meter, diameter of the basket and the circumference of 75-78 centimeters, the weight of 600-650 grams, space and time, control of the ball and scramble for the ball, shooting and restricting the shooting of the offensive and defensive confrontation.
The top is a standard basketball hoop, and the street basketball hoop is meters high.

The height of the basket from the ground is meters.
According to FIBA regulations, the uniform standard height of the basket is meters, and the lower edge of the rebound should be meters from the ground, and the circumference of the basket can not be less than centimeters and greater than 78 centimeters, because the standard basketball diameter is centimeters, so the diameter of the basket should also be 45 centimeters.
In addition, in order to avoid damage to the basketball stand when the basket is dunked, the position of the supporting feet of the basketball stand base is generally made of cast iron, which can effectively withstand and relieve the pressure on the basketball stand when dunking.
Basket making:
The basket is made of a solid iron bar with an inner diameter of 45 cm, painted orange with paint, and needs to be securely mounted above the board, and the part of the hoop needs to be kept horizontal, equal to the diameter of the two vertical sides of the backboard.
In addition, you can use the anti-pressure hoop, which has good characteristics, which can ensure the safety of the players when dunking, and reduce the pressure on the rebound and the hoop to a certain extent.

The height of the upper edge of the basket from the ground front crack is the letter base blind () slippery meter?
Correct answer: B
Turning around without shooting the ball is usually a step, but if you have a good pivot foot, it may also be a good ball. The Basketball Rules stipulate walking as follows: >>>More
As far as I know, according to the aerodynamic point of view, when the car is stationary or driving at low speed, the air velocity passing through the car is small, and the pressure on the roof and the bottom of the car is basically the same, when the car is running at high speed, the air flow speed at the bottom of the car is larger, the static pressure on the bottom of the car is reduced, and the roof is mostly streamlined and can be approximately seen to be in a large space, so the pressure changes little, and the uneven pressure difference between the upper and lower sides causes the distance between the car chassis and the ground to decrease, and the greater the speed, the more unbalanced it is. This is the opposite of the design of the aircraft, which uses the lower part to be streamlined, and the upper part is flat to create a large pressure difference in flight and provide lifting force.
Causes: 1. Mobile phone firmware problems.
2. The wifi parts need to be repaired. >>>More
It's just that the diameter of the earth is relatively large, so people can't feel the arc, and if you get to a high enough height or leave the earth, you can feel the arc.
A few years ago, in Yunnan, Guangxi, and Guizhou, in order to realize the communication between villages and villages, every household installed that satellite antenna, and a few years ago, I sold satellite antennas there, two or three hundred yuan a (, the big seven or eight thousand, used by the Provincial Department of Radio and Television; Later, there were more people, causing chaos, and the country's communication plan for the whole country was incompatible with free installation, and it was bound to be legislated to prohibit individuals from installing at will, but also for the overall situation, unified management of the country's general undertakings! >>>More
