12 Th Century Flying Buttresses

Medieval masons solved this difficult problem about 1120 with a number of brilliant innovations First and foremost they developed a ribbed vault, in which arching and intersecting stone ribs support a vaulted ceiling surface that is composed of mere thin stone panels. This greatly reduced the weight (and thus the outward thrust)...

Shock Waves Air Pressure
834 wordsResearch: Airplanes are an efficient way of traveling to far places. Airplanes are amazing if you know what and how the air keeps the plane airborne. There are three components of flight: aerodynamics, the Bernoulli principal and supersonic flight. Some other things about flight are the four forces, lift, drag, weight, and thrust. One of the basic things you need to know about airplanes is that the places where the plane can balance on one point called the center of gravity. The tail on the plan...

Filling Slot Bearings Single Row Bearing Balls
424 wordsThe object of ball bearings (and roller bearings) is the substitution of pure rolling motion for plain sliding friction. Ball Bearings rely on the rolling motion of hardened steel balls to absorb loads. This rolling motion produces far less friction than the sliding motion. These steel balls are held in circular rows between an outer and inner ring, which have raceways, or slots, grooved into them to guide the balls. Ball bearings are available in both filling-slot and no filling-slot types. Oth...

Action Of The Play Audience Members
792 wordsWhen you ask a person to describe the layout of a theatre to you, most people show you that the stage goes on one end of the building, and the audience goes on the other, facing the stage. Most theater-goers are probably not aware that the space they watch the majority of plays in is not the only way that an audience can be engaged with the actors on the stage. In Shakespeare's Love's Labour's Lost directed by Mark Harrison a thrust stage is used to being the audience closer to the action of the...

Bypass Ratio Engines Low Bypass Ratio Engines Turbine
1,043 wordsThe idea of utilizing the physical principle of reaction on a large scale by means of rockets is usually attributed to China in the thirteenth century. Not until after the Second World War, however, did rocket technology mature to a state which made the idea of space travel a practical possibility, owing largely to a giant step forward during the war itself. Although earliest models of the steam turbine date back as early as the 17 th century, practical applications of the turbine engine had to ...

The compressor of a turbo shaft engine first raises the pressure of the incoming air, which is then guided into the combustion chamber. After being mixed with vaporized fuel and burned, the hot gas expands completely through two separate turbines. The first turbine drives the compressor; the second delivers horsepower to drive the helicopter rotor. The gas is finally released through an exhaust d...

Bleed air is used for aircraft systems such as cabin pressurization and heating, wing leading edge de-icing, and for electronic systems temperature control. The engine itself also requires bleed air both for de-icing the front frame support struts and nose cowl, and for cooling the turbine frame and blades. Guide vanes are used to impose a d...
