Degenerate Cases of Conic Sections: Conics are formed when a plane and a double cone intersect. These intersections can form a variety of conics. These include: circles, parabolas, ellipses and hyperbolas. A circle can be formed from a cone if a plane intersects with the cone at an angle perpendicular to the base of the cone. This circle is also formed by the equation: (x-h)2+ (y-k)2=r2. This equation creates a relation because the collection of points does not pass the vertical line test. To…

Does the number of tiny holes in the parachute affect its descension rate Introduction This experiment will determine if the number of tiny holes in the parachute effect will its descension rate.This science of this project includes newtons second law, drag force, gravity, velocity and terminal velocity . This experiments main focus is air resistance. Project rationale/ purpose In this experiment I will test if having small holes in a parachute help the parachute from falling as fast. This…

In his article “How we Listen to Music”, Aaron Copland (1988) states that music is listened to on three different planes. Copland describes them as the sensuous plane, the expressive plane, and the sheerly musical plane. The reasoning for listening to music for the pure rhythm and harmony is the sensuous plane. The sensuous plane is where “one turns on the radio while doing something else and absent mindedly is engendered by the mere sound and appeal of the music” (Copland). People who apply…

The T-41 (i.e., the military version of the Cessna 172) had a "simple mechanical" flight control system using direct mechanical linkages. Direct feedback of forces acting on the control surfaces to the control stick (or yoke) provided a natural feel. The feedback was by the "seat of the pants". The trim system was a mechanical linkage connected directly to a trim control wheel in the cockpit. There is no warning in the T-41 if the trim was set incorrectly. It is the pilot’s responsibility…

Did you know parachutes come in all kinds of different shapes? The shapes vary from circles to triangles. However which one is the fastest? There are many factors that effect the speed of parachutes. Kinetic and potential, for example, influence the parachutes speed and movement. When a skydiver jumps out of an airplane gravity pulls him towards the ground and he doesn’t have enough air resistance to safety land on the ground. That’s where the parachute comes in! When the skydiver pulls the…

1. Flights of Fancy 2. “It’s really pretty straightforward: flight is freedom.” (136) 3. Foster explained in a story about people with “wings” and those “wings” provide freedom. However, with freedom comes the ones who abuse it. As you can see, the title of the chapter is Flights of Fancy which can explain the stereotypical snotty rich kid everyone hates. This is because rich people are fancy and rich people are very free, but can abuse their freedom to make the wings dirty, as Foster explained.…

Objective: The lab we completed today was “Equilibrium of coplanar forces”. The objectives of todays lab was to study the composition and equilibrium as well as study the rectangular resolution and equilibrium of coplanar forces. Principles being examined: The main principle being examined in this experiment is the fact that several forces that line on a plane and pass through the same point can be balanced by a single force that is passing through the same point. We do this by finding the…

Drag force is an aerodynamic force which acts parallel and opposite to the motion of the object when it moves through a fluid. It is caused by friction and differences in air pressure. There are many factors can affect the magnitude of drag force as with aircraft lift. The drag depends linearly on the shape and size of the object moving through the air. The object’s cross-sectional shape determines the form drag which is created by the pressure variation around the object and affects the…

Most of the time, paper airplanes don’t exactly match other planes. They can either fly upwards, downwards, left, right, or sometimes even straight. No matter what type paper is used, it can never match a professional’s paper airplane. All of this is due to the design of the plane. For example, if the plane is perfectly built but has a round nose rather than a sharp nose, it won’t be able to fly far. The three factors that can make a good paper airplane are aerodynamics, gravity, and balance.…

Fig.\ref{Str_1_T} compares the jet trajectory measurement for the open nozzle configuration at the two blower velocities. Fig.\ref{Str_1_W} compares the weight distribution along the centerline axis, normalized with respect to the total mass distributed. Fig.\ref{Profiles_1}.a shows the centerline profile of the straw distribution on the ground, normalized to their respective maximum weights and Fig.\ref{Profiles_1}.b shows the jet spreading along curvilinear trajectory $\zeta$.…
