How do Aircrafts Fly?

-
To fly in the air, aircrafts need power, which is provided by the engines. They need a lift to rise from the ground and stay in the air. This lift is provided by the wings. The aircraft wings have a special shape called an aerofoil. The top surface of the wing is curved, while the bottom is flat. As the plane cuts through the air, the air that flows over the wing has to travel greater distances than the air flowing underneath the wing, so it has to travel faster over the top. This reduces the pressure above the wing and creates lift At take-off, the engine provides the power to generate lift. The forward thrust of the engines balances the resistance or drag set up by the air.

When were the First Spinning Machines Invented?

-
Image
People in the olden days used to spin thread by hand . They pulled fibres out of cotton and wool and twisted them together into thread. Spinning machines were invented in Britain in the 1700s. These machines had rollers turning at different speeds to twist the fibres into yarn. James Hargreaves in 1764 produced the first successful spinning machine. It was the hand-powered jenny which produced thin yarn. Richard Arkwright's water frame of 1769, powered by water wheels, gave a sturdy thread. Samuel Crompton combined these two spinning machines in 1779 , to make the spinning mule, which could spin many kinds of yarn. These machines were the precursors of the Industrial Revolution .

When were the First Mechanical Clocks Made?

The first mechanical clocks are believed to have been made in China in 1088 AD. Later in 1200s, they were first made in Europe. Such clocks made in Europe were driven by a weight on the end of a cord wound round a drum. As the drum rotated, it turned the hands of the clock. The earliest known clock was made in Spain in 1276 AD and the oldest mechanical clock that still works is in Salisbury cathedral in Britain. It was made in 1368. These clocks had devices called escapements to keep the hands turning at the correct rate, so that the clocks depicted the correct time.

What is a Geostationary Orbit?

Image
Artificial satellites sent from the Earth orbit around the earth. The ones near the Earth orbit faster than the ones far away. A satellite 35,900 Km above the Earth's surface, takes 24 hours to orbit once. The satellite is always above the same point on the Earth's surface as the planet rotates. Geostationary orbit is also called as geosynchronous ' orbit. Such satellites are used to receive telephone and television signals and retransmit them over long distances.

When was Radar Invented?

-
Image
Radar was invented during 1930s. Many countries worked on radar at this time, but the first successful radar was built by Britain in 1935. Radar works by sending out radio signals that bounce off distant objects. The radar set detects the signals that return and produces a picture indicating the position of the objects . British and American scientists worked together to invent methods of using short waves called microwaves.
