Did this dam of China change the speed of the earth? What is a shocking claim of NASA scientists
China Biggest Dam Effect on Earth Rotation in Hindi: China is known for its giant projects and technical successes. In this episode, he has set a new record by creating the world’s largest dam, Three Gorges Dam. This giant structure built on the Yangtzi River of China is not only a wonder of its engineering, but some scientists believe that its effect is so deep that it has slowed down the speed of our Earth’s moving on its axis! It is a matter of concern that China is going to build three times larger dams on the Brahmaputra River than the world’s largest three gorges dam. The Brahmaputra River, which originates from the Chemungdung glacier near the Mansarovar Lake in the Tibet province of China. In China, Brahmaputra is called Yarlung Sangpo. China has already built many big dams on this river and is now preparing to build the world’s largest dam.
Three Gorges Dam: A Technical Miracle!
Three Gorges Dam is known for its vastness and complex engineering, which China is built on the Yangtzi River. The dam was mainly built with the aim of improving flood control, power generation and water transport. Its capacity is so high that it can stop millions of cubic meters of water. This dam is 607 meters high and 2 km long. Let us know how this dam has affected the speed of the Earth:
How the speed of the earth has changed,
According to research by NASA scientist Benjamin Fong Chao and his team, this three gorgeous dam has slowed down the Earth’s walking speed at 0.06 microcecand per day. Hearing this may seem incredible, but it is associated with a scientific event called ‘Moment of Inrtia’.
What happens ,Moment of Inersia,
‘Moment of Insuria’ is the measure of the inertia of a moving object. Take an example to understand this: When an ice skating person moves around with his arms, his speed is slow. As soon as he brings his arms closer to the body, his walking speed increases. This is because the center of mass comes closer to the axis, which reduces the ‘Moment of Insoria’, which increases the speed. Similarly, this rule also applies to Earth. The distribution of mass on the axis of the Earth’s rotation affects its ‘Moment of Insuria’.
How did Three Gorges Dam affect the speed of the earth,
When a huge amount of water accumulates in the three gorgeous dams, this water acts as a large mass on the Earth’s surface. This huge water (about 39 cubic kilometers of water) accumulates close to the equator, slightly away from the Earth’s axis. This incident has the following effects:
- Relating mass: When so much water gets up from the low -lying areas and accumulates at the height behind the dam, it changes the distribution of the mass of the Earth.
- ,Moment of Inersia, Change in: This mass removal of mass increases the ‘Moment of Insoria’ of the Earth.
- Reduction in walking speed: According to the rules of physics, when the ‘Moment of Insoria’ of a moving object increases, its rotation speed (angular velocity) slows down, so that the total angular momentum is preserved.
Due to this principle, excessive water deposition in the Three Gorges Dam has changed the Earth’s ‘Moment of Insoria’ to some extent to some extent.
