put together a complete guide to aerodynamics on my web site. Its important to realize the basics of why paper airplanes fly, and why full size airplanes fly, are identical. They create lift and drag, and are stable or unstable for the same reasons. However paper airplanes look different than most airplanes. The reason they generally look different is for very practical reasons, but not necessarily due to aerodynamics.
A. Since we did not have a lot of money growing up, this was an inexpensive way for us to show some creativity. B. Origami can be a cheap and effective way to entertain yourself, children, and they also make great party ideas. III. According to Christine Petrell Kallevig in her 1991 book Folding Stories, there are six folds involved in make a paper swan.
Check lists are one of the basic seven quality tools used in projects (Bersbach, How to build a good Check Sheet, 2012). There are so many different types and forms for these lists they are often not thought of as lists (Bersbach, The Seven Basic Quality Control Tools, 2011). I have used lists many times to both ensure items for a project were finished and that they were checked and finished properly. I spent a lot of time debating with myself over the topic of this paper to find that my thoughts on the issues for multiple past projects could be defined and refined by using control and Pareto diagrams along with some of the other seven tools that really were not mentioned in this course to any degree. Single project however, do not require the depth that these other tools use for the project itself.
The research will also cover the advance technology that was used to create this massive structure without machines of mass power. Many researchers theorize that there might have been external ramps and cranes to lift the blocks that weighed 2.5 to 15 tons each. Others theorize that there would have only been the use of ramps, and that the stones would have been hauled up. Another mystery of this pyramid is its perfect geometrical alignments. This pyramid has the “designed geometry of an equal lateral triangle and a 52-degree incline”
Even today, with all the methods of planning and construction equipment, it would still be very difficult to build the pyramids. Joseph Davidovits is a French materials scientist and is known for the invention of geopolymer chemistry. He theorized that the blocks of the Great Pyramid were not built from carved stone but mostly from a form of limestone concrete or man-made stone. This was not a concrete made with plaster, nor is it a modern cement of the Portland type used to agglomerate ground up stone. Davidovits believed his agglomerated stone theory was the only one that was really holistic.
Ms. June Parachutes and Aerodynamics 8H Bell 2 12/3/14 Parachutes and Aerodynamics How have parachutes been used overtime and why are they important? The use of the parachute has varied for different needs and they are important because some of the uses were in historical events like World War II. To learn about parachutes fully, people have to understand the philosophy of aerodynamics, the history, the varying materials, types, and the vital characteristics. One person who most people think of as a famous artist during the Renaissance actually came up with the idea of a parachute, but had no impact on the development or creation of it. How can that happen if the person came up with the idea?
It’s an experimental form of art as well. Fractal art is just another form of art. Fractal art is not drawn or painted by hand it is usually created with fractal generating software. Fractal couldn’t have been invented without computers because of the capabilities they provide. Fractals are made by applying iterative methods to solving non-linear equations.
Published: February 2011 Evolution of Feathers The long curious extravagant evolution of feathers By Carl Zimmer Most of us will never get to see nature's greatest marvels in person. We won't get a glimpse of a colossal squid's eye, as big as a basketball. The closest we'll get to a narwhal's unicornlike tusk is a photograph. But there is one natural wonder that just about all of us can see, simply by stepping outside: dinosaurs using their feathers to fly. Birds are so common, even in the most paved-over places on Earth, that it's easy to take for granted both their dinosaur heritage and the ingenious plumage that keeps them aloft.
9. Find the average time for each clay with different mass to hit the ground. 10.Find the speed of the parachute in each trial and the random uncertainty from the repeat trials. 11.Plot a graph of mass (x-‐axis) against time (y-‐axis) to look for a relationship. If the ﬁrst graph is not linear it will be necessary to further process the data and plot further graphs to try to ﬁnd a
The Pyramids of Giza Hassina Driss Strayer University World Cultures 1 HUM111 Professor Dolores Belew Sunday November 2nd Introduction. There is a lot of mystery surrounding the pyramids of Giza, and many questions remain unanswered even nowadays: such as: what is the purpose of these monuments? Why the particular shape? And how were the heavy stones lifted all the way up to the top? Many theories and hypothesis were made, even published.
