2132 - Book meme

Via melissasutton:

* Grab the nearest book.
* Open the book to page 56.
* Find the fifth sentence.
* Post the text of the next seven sentences in your journal along with these instructions.
* Don't dig for your favourite book, the cool book, or the intellectual one: pick the CLOSEST.

From the Pilot's Handbook of Aeronautical Knowledge:

Since the weight of the horizontal surfaces is at the top of the vertical stabilizer, the moment arm created causes high loads on the vertical stabilizer which can result in flutter. Engineers must compensate for this by increasing the design stiffness of the vertical stabilizer, usually resulting in a weight penalty over conventional tail designs.

When flying at a very high angle of attack with a low airspeed and an aft CG, the T-tail airplane may be susceptible to a deep stall. In a deep stall, the airflow over the horizontal tail is blanketed by the disturbed airflow from the wings and fuselage. In these circumstances, elevator or stabilator control could be diminished, making it difficult to recover from the stall. It should be noted that an aft CG could be a contributing factor in these incidents since similar recovery problems are also found with conventional-tail aircraft with an aft CG.

Since flight at a high angle of attack with a low airspeed and an aft CG position can be dangerous, many airplanes have systems to compensate for this situation.

Ah! You already know about the Piper Traumahawk.

I can't do this meme very well. So far I've picked up three books, and two of them have no page 56, and one has a bus route map on it and no sentences except footnotes for the entire rest of the book.

As i'm not a fan of memes, I'll just post it here.

La Alpoj formas belegan naturspektaklon. La aero estas eksterordinare pura - tiel purega, ke malsanuloj venas el tuta Euxropo al Svislando. La granda komforto kaj bonega kuirarto de la svisaj hoteloj estas mondfamaj. Konstante okazas interesaj popolfestoj, kun belegaj kostumoj; ankaux ekspozicioj muzikfestoj, sportfestoj, lagofestoj, florfestoj, k.s. Vere, turismo estas la cxefa industrio de Svislando! Ni menciu ankaux la luksajn butikojn, koncertejojn kaj teatrojn, kaj la gravajn universitatojn, muzeojn, kaj bibliotekojn.

Kiel mi iru al Svislando?

Yes, my Teach Yourself Esperanto book was the closest thing to my computer. :)
