    Physics of Lift

    Lift is a commonly used term to describe "something" that results in objects moving upwards against the force caused by gravity. This "something" is actually a force in itself. Lift is one of the four main forces that act upon all objects that move through the air. These four forces are: # Lift - an upward force on the object # Weight - a downward force due to the acceleration of gravity # Thrust - a forward force (propulsion) # Drag - a force caused by resistance that acts in the opposite direction

    The common explanation given to those curious about how an airplane wing produces lift uses the Bernoulli Principle. This is the concept that because of the airfoil shape of a wing, the air traveling over the top of the wing must travel faster than the air going under the wing because it has to travel a farther distance. The resulting difference in pressure between the two (higher pressure under the wing) creates lift, keeping the plane in the air. This explanation is unsatisfactory in a number

    How to Lift Heavy Objects It is important to understand how to lift objects correctly. The results of improper handling of materials may result in a painful hernia, a strained or pulled muscle, or a disk lesion. The following rules are to be observed when lifting heavy objects. 1. Do NOT lift an object if it is too heavy or too bulky for good balance. Get help or use mechanical aids such as a dolly or hand truck. 2. Keep the load as close to the centre of your body. The farther the load is from

    Lift the Cuban Embargo In 1959, revolutionaries nationalized Cuba’s wealth and did not compensate U.S. companies for our efforts to fight against the rebels. They did, however, repay corporations from nations that did not fight. Because of this seizure of our property, the Cuban embargo was put into action. In fact, Cuba is the only country in the western hemisphere which the U.S. government has persistently and actively used a full economic embargo as a dominant policy tool in an attempt

    “that Cuba has been developing biological weapons of mass destruction.” Figures. Finally, It is clear that there is a serious issue regarding poverty in Cuba that directly results from the forty year old sanctions. It would benefit both countries to lift the sanctions in terms of trade, immigration and development. The sanctions have so far proven unsuccessful, and are just hindering the Cuban economy. Despite all of these points, it seems doubtful that the doors to Cuba shall be unlocked, and that

    factors which are lift, weight, thrust, and drag Lift is the upward force created by the effect of airflow as it passes over and under the wings. It supports the airplane in flight. Weight opposes lift. It is caused by the downward pull of gravity. Thrust is the forward force which propels the airplane through the air. It varies with the amount of engine power being used. Opposing thrust is drag, which is a backward, or retarding, force that limits the speed of the airplane. Lift is the key aerodynamic

    Bok-What? Farming Gets a Face-Lift 1. New Jersey: home of the indelible and intelligent Jersey cow, whose milk is less forthcoming than her sister Holsteins around the country, but richer and creamier, nonetheless. Then there are the fields: acres and acres of Jersey corn stretching up towards the hot summer sun, basking in its glory, waiting patiently for the day when man will enter with his massive harvesting machines, collecting ear upon ear in a dizzying display of mechanized efficiency

    wing design and tail design originates from the primary function of the tail which is different from the wing. The primary function of the wing is to generate the maximum or substantial amount of lift, while the tail is designed to operate normally at only a fraction of its ability to generate the required lift potential. During a flight mission, if at any moment the tail reaches its maximum angle of attack which refers to the tail stall angle; is an indication of design process error.[1][2]The tail

    It's Time to Lift the Embargo Against Cuba I waited an hour and a half for my first camello. It was too hot at the bus stop to do anything but stand and stare at the corner where the camello-a semi carrying a small jail, as a friend described it-would turn onto 23rd. The line was long, maybe forty people. When the camello finally arrived, the line broke into a desperate mob. I let myself be pushed inside. A pregnant woman in front of me panicked and began swearing and throwing elbows. I
