Theory of Longitudinal Static Stability Stick Fixed Stability (tailless aircraft) An aircraft that has elevons (combined ailerons and elevators) e.g.‚ Concorde is governed by slightly different equations. The effect of the tab angle is usually ignored as most tailless aircraft have powered controls and so no tabs. The lift equation therefore becomes Moments about the cg give us: For TRIM‚ the elevon angle to trim is [pic] For STABILITY it is clear that the aerodynamic

today ’s culture‚ electricity is a vital part of functioning as a society. Simple tasks‚ such as waking up at a designated time or enjoying a piece of music‚ are accomplished currently via electronic means. One only needs to consider the consequences of a relatively short power outage factories close down‚ phones and computers go dead‚ traffic slows to a crawl‚ food spoils in refrigerators to accurately observe how power-dependent our society has become. However‚ electricity is a constantly developing

effect was named after the scientist Luigi Galvani‚ who investigated the effect of electricity on dissected animals in the 1780s and 1790s. While experimenting in his lab‚ his scalpel touched the body of a frog‚ and he saw the muscles in the frog’s leg twitch. At that time he thought that he had discovered a new way of forming electricity. The term is also used to describe the bringing to life of organisms using electricity‚ as popularly associated with the 1831 revised edition of‚ Mary Shelley’s work

Filipino Scientists Contribution in the field of electricity Gregorio Zara Holder of doctorate in physics. Among Filipino Scientists‚ he is perhaps the most notable in the field of electricity. Zara formulated the Law of electrical resistance or what is known as the Zara Effect. This law states that all moving contacts between conductors produce a resistance to the passage electrical current which may be kinetic or permanent electrical resistance.

conditions affect the formation of a static charge? Date: 2/1/2013 Statement of Problem: Do certain weather conditions increase or decrease static charge? What can be done to reduce or eliminate the static charge? Hypothesis: In reading up on this topic I learned that cold dry weather seems to increase static charge. It is a known fact that if humidity is above 30% it will reduce the static charge. Therefore‚ by adding water to the environment static charge is reduced or eliminated.
