of a good due to economic changes. The outcome of any situation determines the price of a good. There are three types of elasticity of demand that each good has‚ which are elastic‚ a situation in which the supply and demand for a good or service can vary significantly due to the price (Elastic Definition‚ 2012); unitary elastic‚ a situation where a change in one factor causes an equal or proportional change in another factor (Unitary Elasticity‚ 2012); and inelastic‚ situation in which the supply

Aeronautical Engineering My long-standing fascination with aircrafts began with my favourite toy helicopter. Since then I have made a model plane of a radio controlled spitfire Mk2 and managed to fly it. My fascination has been followed up with literature and resources; further developing my understanding and interests in the architecture of an aircraft. Books such as ’The Aerospace Chronology’ provided some insight into technological advances that have produced safer‚ faster and more agile planes

ELASTIC DEMAND Demand is elastic when the percentage change in the quantity demanded is greater than the percentage change in the price‚ i.e. when: Percentage change in the quantity demanded > 1 Percentage change in the price Example A fall in the price of cotton in Antigua and Barbuda from $20 to $18 causes the quantity demanded to increase from units to 150 units In the figure above‚ the price range $20 to $18‚ demand is elastic. Percentage change in the quantity

ELASTIC BAND PRACTICAL Introduction The elastic band‚ or rubber band as it is sometimes known‚ is an item that is generally taken for granted today. Because of their unique elasticity‚ they have many purposes. The main purpose is for storage but they can also be used for crafting. Elastic energy only lasts for a short period of time but is comparatively strong. Aim To investigate the amount that a rubber band is stretched when consistently increasing amounts of weights are placed Hypothesis

The Airfoil & Theories of Lift Airfoil Definition: Have you noticed the curved shape of a bird ’s wing? An airplane ’s wing is curved also. A wing is designed for flight. It has a special shape called an airfoil. The airfoil shape provides a lifting force when air flows around it. Airfoil shapes can be found on wings‚ fans and propellers. Importance: An airplane’s airfoil plays a very important role in lifting the aircraft. The airfoil is designed to increase the velocity of the
