Why is the red lantern in the square square still unable to move? Behind it is full of black technology!
For our Chinese people, when we meet some happy events, we will hang red lanterns on their own doors to celebrate. The red lanterns will not only make the scene look more joyful, but also our national culture. On the occasion of the 70th anniversary birthday of the motherland, red lanterns were also hung up high in the square. It is hard to understand that these red lanterns remain motionless in the wind and will not be swept away by the wind as ordinary lanterns. Why are these lanterns so? Xiaobian thinks you can have a look.
These lanterns are 5 metres in diameter and 4.2 metres in height. The reason why such a huge volume can not move is that the technical standard of large lanterns completely adopts the space standard. At the same time, the rope used to support the lanterns is made of square fibre rope, which is the material used for the recovery of satellite spacecraft. Although only 6 millimetres thick, it can withstand 800 kilograms of force, so the rope is able to withstand 800 kilograms of force. The safety of lanterns has been ensured, and the expertise in the fields of aerodynamics and theoretical mechanics should be integrated in order to ensure that lanterns are still on the Tiananmen square.
