Recommended: Physics of a catapult

Essentially the plan for the catapult would have been the same. Measurements for the catapult are the same just in wood. So for lumber I would have gone with an eight foot long of 1.5in x 1.5in would have saved a cent over PVC. For my swing arm I would needed something thinner to be able to swing more freely. I went with a foot and a half of 1-in x 2-in which out of an 8 foot long log that cost ninety six cents priced out to be sixteen cents. Since I didn’t need elbows for wood and elbows were the most expensive material out of the PVC catapult. Instead I’d use screws to hold the corners together. I estimated that I needed twenty screws, so two screws in every corner to make it more secure. This like the elbows ran up to be three dollars in

  • Science Olympiad: The Boomilever

    1281 Words  | 3 Pages

    All in all, this Science Olympiad event is much more than gluing some sticks together. There are many factors to consider, and simply putting together a boomilever on a whim and hoping for it to be efficient is not very realistic. There are many technicalities and terms associated with a successful device. Some of the main factors come from the materials used, and where they were used on the structure. Some are best used in one place, or another. All of this must be taken into consideration when deciding on how to best utilize the physics and forces applied to the boomilever. As it is a simple machine, it dominates in simplicity for a somewhat daunting task. Laws such as the lever law and Euler’s Buckling Theorem come into play when testing and competition begins. A structure of wood and glue surely has much more to offer than meets the eye.

  • An Analysis Of Ace Crusher By Dalton Derksen

    In his poem “Ace Crusher”, Dalton Derksen explores the idea that in order to overcome restraints in our technology-based world, people must push themselves to encounter what is intimidating and feared in order to become stronger. In today’s world, the lives of youth and young adults revolve mainly around technology. Due to the accessibility and ease of technology in today’s world, people tend to abstain from experiencing new things and branching out into anything that scares them, as hiding behind screens promotes socializing with what is familiar. Derksen illustrates and mocks the idea of the pain and fear surrounding trying new things in our advanced world in this poem. He ridicules the fear surrounding new experiences by using symbolism,

    The word trebuchet originated in France, but contrary to the name, the early siege weapon actually originated in China. The original trebuchet was made in 300BC. The trebuchet was made as a way to attack over enemy walls or fire at large groups of enemies running at the user. The Chinese had a design in which good ol’ fashion man power was used instead of a counter weight. There weren't very many advancements in the Chinese trebuchet besides the use of different woods. This trebuchet tended to be the least accurate out of all of the other models. This model is known as the traction trebuchet.

  • Experiment: A Breaching Experiment

    928 Words  | 2 Pages

    For my breaching experiment, I decided to break the social norm of looking at someone while engaged in conversation with them. Today, it is socially unacceptable and impolite to avoid looking at someone when talking to them. The background assumption for a typical conversation is that direct eye contact will be made more often than not; otherwise social norms are being violated. Avoiding eye contact during an exchange tends to dehumanize the person that is not receiving the eye contact. It is impolite and offensive, not looking at someone who is talking makes it seem as though the topic being discussed is unimportant. For my research experiment I would constantly talk to someone without initiating eye contact, or with my back facing toward the subject, not turning around or making eye contact until I had to ring up their order or make the drink for them. This research is important because it uncovers what happens when the social norm of

  • Projectile Lab Essay

    The purpose of the projectile lab is to test the validity of the law of conservation of energy. The application of this law to our everyday lives is a surprisingly complicated process. Conservation of energy states that energy cannot be created or destroyed, but that it can be transferred from one form to another. Consider the projectile lab from document A that this essay is based upon. In an ideal experiment, the projectile is isolated from everything except the gravitational field. In this case, the only force acting on the particle is gravity and there are only two forms of energy that are of interest: the energy of the particle due to its motion (defined as kinetic

  • Terminal Ballistics

    The use of firearms in crimes has been rapidly increasing, and it seems that one cannot turn on the news without hearing that some crime had been committed with a firearm. Using ballistics as evidence is a way for law enforcement officers to help solve crimes and potentially capture criminals. Ballistics is a very complicated science, where every single detail matters. Every micro-measurement makes a difference when analyzing firearms and ballistics. The most complicated part when solving a crime involving firearms is the fact that no one can recreate the same exact shot. Even though it is an impossible task to do, experts can still duplicate scenarios and environments similar to the original crime, giving law enforcement more evidence to put

    The author further explains how once the Romans gained knowledge of the weapon, they innovated it further by adding wheels to the catapult for easier mobility. The author describes the Ballista as “ a giant crossbow, used for shooting large arrows or darts. It was a powerful anti-personnel weapon, capable of transfixing several armoured men with a single dart”. The ballista works by the tension created by skeins of rope or animal muscles or tendons, and the wooden structure created by the manufacturer. Another important catapult used during wartime was the Perrier. In an article on “codesmiths.com”, the author describes it as “Perriers relied on simple muscle power for their action. This is a three rope example, powered by six soldiers pulling on it. There are stories of large perriers using up to two hundred soldiers.” We get an idea as to the vast variety of catapults being used during the time. Even under a subcategory of a type of catapult, we have several dozens of different types. The author goes further in detail, and shows how the Perrier, unlike the other catapults, could only fire stones weighing under 10 lbs. Although there was a weight limit on the Perrier, the catapult was known for its high rate of fire, firing about
