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

Victorian moral values‚ male superiority and the influence of aristocracy. This is further illuminated by Du Maurier’s Rebecca where male dominance and misogyny mean only the woman will pay. As a woman in the midst of an undeniably patriarchal society‚ Tess is unable to escape the social structure. Tess epitomizes the case that the innocent pay for the guilty. Similarly‚ Rebecca faces a fight against the pressure of the Victorian society to maintain a perfect marriage‚ but fails to succeed. Both

Stretching has four types which is dynamic‚ ballistic‚ static stretching and proprioceptive neuromuscular facilitation Ballistic stretching is a swift or fast bouncing stretch in which a body part is going with momentum that stretches the muscles to a highest. Muscles react to this type of stretching by contracting to protect itself from over elongated. Dynamic stretching is a movement stretch. With performing downtempo controlled movements through

Dynamic Earth Has the Earth been static since the beginning of time? Well‚ Earth hasn’t been moving vigorously but it is changing at a steady rate. New geological features‚ rock formations‚ and locations of plates all rise and demolish some in a lifetime and others over a span of millions of years. Earth is dynamic; it constantly progresses and doesn’t rest. Through the churns and molds‚ the twists and turns‚ Earth is active because of plate tectonics and the rock cycle. The ideas

Hazards of Static Electricity; Lightning Lightning is a massive electrostatic discharge between the electrically charged regions within clouds or between a cloud and the surface of a planet. It is the sudden high-current discharge caused by the atmosphere’s electrical breakdown. Lightning is also one of the most deadly natural phenomena known to man. Lightning is an electric current; thus within a thundercloud up in the sky‚ many small bits of ice (frozen raindrops) collide into each other as
