How to make a car track, Lego tutorial

Method: build a track with Lego toys, make a preparation pole, and put a flag-waving villain on the side , let the car wait behind the preparation pole, and then set a finish line at the other end, and then you can get ready to start! Tape runway Suitable for age: 3-6 years old. Materials: white tape, color cards, watercolor pens, etc.

The connection between the particles is very simple. The bulge above the particles and the groove below complete the connection between the parts. Using simple particles, it can be assembled into cars, houses and cities. As long as there is an idea, everyone can complete a unique work.

First, build the body part.Then there is the construction of the tail. Finally, the head, plus the long pointed mouth in front. Finally, a cute little seahorse is completed! Lego is a kind of plastic building toy.

The Lego Decryption Box 4×4 production tutorial is as follows: prepare the required Lego blocks and parts. Choose the right blocks and parts according to the design drawings or your own ideas. Design the shape and structure of the mecha. You can draw a sketch first or use computer-aided design software for simulation.

Prepare simple blocks: choose blocks with appropriate size and shape, such as rectangular blocks, square blocks and wheels. Create a tank base: assemble the rectangular blocks together to form the main structure of the tank base. Make sure that the base is stable enough to support other components.

First, install the parts of the guard wheel above the wheels of the chassis;Then fill in and flatten the parts below; extend another grid to the back of the Lego tire at the back of the chassis. In this way, it is assembled into a chassis.

Is the inner side of the curve of the car runway necessarily lower than the outer side

1. In order to increase the centripetal force required by the car when turning, it is conducive to turning and make the car not easy to overturn due to too steep a sharp curve.

2. First of all, the road surface with sharp bends is usually lower on the inside of the curve and slightly higher on the outside of the curve (look at the Panshan Highway). There are several advantages of driving on the inside of the curve: from the perspective of safety, it greatly avoids the possibility of driving with the oncoming car; saving distance; except for the left turn.

3. When the car turns on the horizontal road, the road faces the wheels.Static friction is provided to the centripetal force. Among them, the front wheel is subjected to the static friction of the road surface, which changes the direction of movement. Other parts maintain the original state of motion due to inertia and continue to move forward. If the speed is too high, it may cause a side rollover.

4. This design is mainly to protect the road. When the car turns a corner, the inward centripetal force is generated by the inward tilt of the car, which can reduce the friction of the car on the road and protect the road, which is also good for the car.

5. The turning point of the highway is high and low on one side to generate a centripetal force to provide turning and ensure driving safety. For any object that makes circular motion, the direction of the speed must change at all times. In order to change the direction of the object's speed, a certain size of force is needed, which is the centripetal force.

6. FirstFirst, slow down the speed and drive into the entrance of the first curve. On each curve, drive according to the method of the outer side first, then the inner side and then the outer side. In the meantime, you can add a little throttle. When passing the last curve, once you see the exit of the curve, you can correct the direction, fully accelerate, and drive away from the curve in a straight line.

How to arrange the Swell three-dimensional calculation car runway

First arrange it according to the flat plate, and then select the board, right-click, the board body becomes oblique, and you will follow the command line prompts.

You can arrange it with stairs and choose the type of stairs according to the type you need.

Determinate the project point group according to the arranged alien base atoms, and further determine the project group and space group. Use the indetermable representation (IR) and matrix representation (MR) methods to calculate the Swell calculation.For specific methods, you can refer to relevant quantum chemistry textbooks and papers.

Take stock of the world's famous car test tracks, one on the list in China

German The country's Nürburgring track is probably the most famous track in the world, and anyone can drive it. The Nürburgring Circuit in Germany is also a popular destination for global car manufacturers to test the endurance of new cars.Lamborghini Aventador SVJ competed for the fastest mass-produced car circle at 6:44:97, which has become the badge of honor for fast cars.

Founded in 1996, Zhuhai International Racecourse is the first international racetrack in China to meet the standards of Formula One of the International Automobile Union. At the same time, the first international automobile competition in the history of the mainland was held on the track.

ROC World Car King Competition: Race of Champion, abbreviated as ROC, is the finale and year-end celebration of the world professional racing industry, gathering people from the world's F1 racing, WRC, NASCAR series and WTCC and other worlds. The top players of the top motorsport in the world.

China RV Championship (ChIna Touring Car Championship, abbreviated as CTCC), CTCC is the first racing brand in China. The only FIA supports national RV events is the Class A sports event included in the annual competition plan of the State Administration of Sports.

Self-driving car runway standard

1. Build a car: First of all, build a rectangular body with Lego bricks as a blue thunderblock chassis. Make sure that the car body is stable enough to support the whole deformation process. Install wheels and tires Install Lego Technic series wheels and tires in the four corners of the car body so that Blue Thunder can run on the ground.

2. Decisive height (DecisIon height) is an important parameter in the aircraft's autonomous driving system. It refers to the lowest height above the runway during the instrument landing process, before the aircraft decides whether to make a further landing or carry out the re-flight procedure, which is usually represented by height (feet).

3. Large sidewind landing is a highly demanding driving technique. Because of this, the airport will be closed when the side wind exceeds the standard. The side wind landing mainly adopts l flat flow (PL) correction and side slip supplement.

4. For ILS, just use automatic driving to aim: 1. Enter the ILS frequency you want to land and run in the radio panel NAV1 position, and use the exchange button to activate it. The ILS frequency can be viewed in the map.

5. The plane fromWhen driving, fly to the runway in order to maintain a certain height (such as 1000 meters) and a certain angle (such as an angle of 30 degrees with the runway). The plane intercepts the signal of the ILS system one or two kilometers directly in front of the runway. The direction keeping light is turned off, and the plane automatically adjusts the direction to aim at the runway.
