pattern continues until the aerofoil reaches a point where the increase in angle of incidence no longer produces increase in lift force‚ this position is called the Stall. The theory also predicts that up to stall angle‚ the air circulation around the aerofoil is normal‚ it travels above and below the aerofoil from front to back. After stall angle however‚ a wake is formed above the aerofoil causing air above the aerofoil to recirculate to the front. Apparatus The apparatus used for this lab experiment

Abstract This paper will discuss the waffler employee and how does it compare to a hasty person. The term “waffler” generally refers to an individual who has a tough time making and sticking to decisions. Introduction A waffler is a person that stalls and changes his or her mind often. Most of the time‚ a “waffler” means well but fears making the wrong decision. I honestly don’t see anything wrong with a person not wanting to make the wrong decision. Just be mindful of the consequences. Waffler

Andrew MacGillivray January 31‚ 2013 Golf Fundamentals Anthony Back Spin and Bounce Backspin: Is the backward rotation of the ball on its horizontal axis. Back Spin is influenced and is determined by the loft/degree of the club face‚ the angle of your approach‚ and the speed or velocity of the club head. To create back spin on you must strike the ball below the horizontal axis. The trajectory of the shot involves an upward force that lifts the ball. A well struck shot will result in a large

Materials: Balsa wood‚ ruler‚ protractor‚ balsa wood glue‚ razors‚ rubber band‚ paper‚ washers (used for nose weight)‚ and writing utensils. Distance or Duration? The very first decision I have to make before I explain my design of the balsa wood plane is to decide whether I should try to build a plane that competes for distance or for duration. After thinking about what to pick‚ I decided out of the two‚ the better one to compete for would be duration. The reason why duration is the better option

Stalls and Spins Stalls and resulting spins have caused aircraft accidents since the beginning of flight. Even though airplanes have evolved to have better stall characteristics‚ stalls and spins continue to be a leading cause of accidents (Landsberg). A stall occurs when airflow separates from all or part of the upper surface of a wing‚ resulting in sudden loss of lift. This is caused by exceeding the critical angle of attack (angle of attack is the angle between the relative wind and the chord

Figure 1 below shows the change in magnitude of the steady state acceleration with time. This graph complies with Newton’s second law as the force applied is equal to 1 and the mass remains constant so and an acceleration of one is expected. I also tested this by changing the value of the force applied‚ to a value of 2‚ which in theory should give and equivalent change in the acceleration‚ to a value of 2. From Newton’s second law: it can be seen that as the force varies‚ provided moment of inertia
