TAKEOFF SPEED OF AN AIRCRAFT, MACH SPEED AND ACCELERATION GROUP MORTAL

La velocidad de despegue de un avión comercial, va a depender de:

1- Del tipo de avión.
2- Del peso de despegue.

Mientras mayor el peso de despegue, mayores las velocidades. O sea que cada vez que uno de estos aviones despega, se deben calcular las velocidades para hacerlo, considerando además del peso las características de la pista, la temperatura, presión atmosférica and wind.

To give you an example, an Airbus 340-200 with a takeoff weight of 180 tons, off to 138 knots (256 km / h) approx. The takeoff speed of a plane is 125 km / h. If your car had wings terminaríais flying over highways, so do not run well ...

Sound travels at 340 m / s, equivalent to 1224 km / h. Exceed the speed of sound is going faster. When this happens it breaks the train of sound waves emitted by the plane and you hear the thunder, now the waves emitted by the plane behind the plane are not around ... Normally, flight speeds are classified according to their number Mach: Subsonic

less than 0.7 (less than 856 km / h)
transonic between 0.7 and 1.2 (between 856 and 1468 km / h) between 1.2 and Supersonic
5 (between 1468 and 6120 km / h) Hypersonic
greater than 5


The mass of the Earth creates a gravitational well: that a body can escape the gravitational force has to reach a top speed at 11.2 km / s. This speed is called escape velocity. If the ship is manned, its acceleration should not differ greatly from the value of 1 g (9.8 m / s ²), it is the acceleration to which the human body is used. While there have been reports of people able to withstand accelerations up to 15 g, when the body is subjected to prolonged periods of free fall cause nausea, muscle weakness, reduced sense of taste, poor absorption of calcium, and other symptoms . What happens to the astronauts? must be trained to changes in acceleration to suit your body and its functioning.

Pock Marks From Chicken Pox

COMPLICATED WITH LYRICS (SOMETIMES): LINKIN PARK

Although you may not believe me I like loud music and the pachanga cantaditas as you call them now. I will be more, but I know the group that I present below. Not knowing what to choose karaoke video, I have set the most I like. My favorite is Faint (last). Linkin Park are a type of music Methal rock with a light touch of r'n'b (also love rap) and some electronic music.
I'm not going to put grammar that you can learn it and completing the course does not make much sense, just say that some of his lyrics are difficult to translate and understand. Have become famous this year thanks to the main theme of the movie "Transformers."
morning I wait for the final review and finish the last issue, not miss it. Anyway, happy weekend and grab the book before anything else, you can not fail now.







And this is the song that I like most about this group: Faint



Dedicated to Alejandro and Javier, who also like a lot ...

Can I Have A Pet Platapus

THE PHENOMENON OF TIDES

Tides are ups and downs of sea level due to the influence of the force of attraction between Earth and Moon, the Sun also influences is because not only it but also to force centrifugal caused by the fact that the Earth rotates on its axis. The fact is that talk of a spring tide when aligned Sun-Earth-Moon or Sun-Moon-Earth, where the ups and downs are very diligent, and talked of neap tides when the 3 bodies are at right angles, that happens several times a day.
The first video is not very explanatory but very simple, the second is more complete but longer and heavier to understand, you decide what to see. Do not stand in doubt, watch the two videos ...
