Egg Crash Project Paper
The purpose of this project was to understand the forces, momentum, and energy a contraption would experience during an impact from a pendulum at 5, 10, 15, 20, and 25mph. The project was required to hold and protect 2 raw large Grade A eggs from each pendulum impact respectively.
My project consisted of a simple set of materials: a 30cm by 20cm cardboard box, a toilet paper roll, industrial glue, 2 rubber bands, 4 water bottles, 2 Oreo cookie trays, packaging tape, and lead shielding sheets. The lead sheet was flattened, form-fitted and glued on the inner bottom of the cardboard box. This was done in order to provide the box a low center of gravity and to meet the minimum mass of 1 kg. Glued to the lead sheet was

a toilet paper role cut in half, which housed the eggs during each test, and a rubber band was used in order to keep the eggs from flying out of the toilet paper roll. The flaps of the box were also glued together in order to prevent them from collapsing during testing. On the outside of the box, I taped an Oreo cookie tray and 2 water bottles on the shorter side of the box, then again on the other short side of the box. On the day of testing, I first unscrewed the caps off the water bottles on one side of the cardboard box, which was done to increase the time of impact the pendulum had on my project, in order to decrease the velocity, or the speed of the pendulum in a given direction.
For each test, I was required to calculate the height of the pendulum required in order for it to have the same mass, or the quantity of matter affected by the external force of gravity, as my project. To find the height, it required understanding the process of the pendulum hitting my project step by step. As the pendulum is pulled back, it has its maximum potential energy, which is the energy possessed by a body by virtue of its position relative to other objects. When the pendulum is let go, it loses potential energy while gaining kinetic energy, or the energy that a body possesses by virtue of being in motion. At the bottom of the swing, kinetic energy of pendulum is the greatest because the change in potential energy equals the kinetic energy at the bottom of the swing. As the pendulum hits my project, there is an impulse, a force acting briefly on a body and producing a finite change of momentum, between the pendulum and project. As the pendulum hits my project, the project carries the momentum of the pendulum with it. By working in reverse order, the height of the pendulum required was
found. Some observations that I made were that the air resistance on the box increased with each test because the distance traveled by my project increased with each hit. Also to note was that since I uncapped the water bottles, it created an inelastic collision with the pendulum. An inelastic collision is a in which kinetic energy is not conserved due to the action of internal friction. In other words since my bottles absorbed some kinetic energy from the pendulum, versus an elastic collision, a collision that has the same total kinetic energy before and after the collision, which could have happened if I left the caps on the water bottles.
My task is to investigate the factors that affect the terminal velocity of a falling object.
Dr. Seuss wrote and illustrated “Green Eggs and Ham,” a book loved by all children as it conveys the message of not judging something by its appearance. The illustration style that Dr. Seuss uses pushes the plot of a story forward giving notice to action, color, and tension within a picture. In addition to telling us what we need to hear Dr. Seuss also shows us what we need to see. Every page of “Green Eggs and Ham” is beautifully exemplified with double spread illustrations that are used throughout the book. In this way, the words feel like a part of the world Seuss is building instead of being autonomous; like yin and yang, without one the other would seem incomplete.
Introduction: The purpose of this experiment was to find how changing the angle and velocity would affect the distance the object went, height the object went, and time the object was in the air. Before this lab I could not tell how the angle and velocity would change the results. I needed to figure out what angle and what velocity made the object go farther or make it stay in the air longer. I also found mass will affect the height and distance. I used the site Galileo and Einstein to figure out these factors. (Fowler, M)

Pigeon’s Egg Head (The Light) Going and returning from Washington was painted by George Catlin in 1837-39. It is a 29 x 24 inch oil painting on canvas, which is a medium size picture that anyone can mount on their modest wall. The two men facing in opposite directions from each other are the most visible figures from a distance. But if one is to look carefully close to the artwork, he or she will notice small details which are positioned to help the viewer communicate with the subject of the painting and the fact that the subject is one instead of two persons. The colors are not very bright, nor are they very dark. They are just right in between. This painting portrays the extraordinary changes an Assiniboine warrior underwent by comparing
From the data table, we found that the more paper clips the faster it will fall taking average 2.10 seconds to reach the ground for the class when the whirligig had 4 paper clips on it. However, when the whirligig had only one paper clips it took an average of 2.4 seconds to fall to the ground for the class. This happened because the more something weighs, the greater relationship it has with gravity. The more weight something has the less air resistance can pull up on it and counter gravity but when less are used less gravity is pulling down on it making it float more. Which why fewer paper clips used on the whirligig the more time it takes to fall to the
To investigate the affect the material of a ball has on the bounce height of that ball where the drop height (gravitational potential energy), temperature, location, ball, and air pressure of the ball are kept constant.
4. Make the displacement 30cm by pulling the bob 30cm away from the center. Do this with a meter stick.
I will address how Newton’s Law applies on the bearing loads of a structure, the weight transfer of loads throughout the structure, the consequences of a mistake in calculating the load a structure can hold and how the weight above ground has to be supported by the soil below.
One sunny morning a friendly lady named Mrs. Majeska which lived a happy life. Mrs. Majeska lived in a small cabin house that sat at the end of one path and at the beginning of another path. The left path leads to the city. The right path led through the woods and meadow that led to the ocean shore.(5). One day she went out to go find driftwood for the kindling and hoping she could find some leeks for her soup. (6).
The important factors to be take into consideration in aircraft structures are strength, weight and reliability which determine the requisites to be met by any material used in construction or repair of the aircraft. Airframes must be light in weight and strong. All materials used in construction of an aircraft must be reliable. Reliability minimizes the possibility of hazardous and unexpected failures. Many forces and structural stresses act on an aircraft when in flight and on ground. When it on ground, the force of gravity engenders weight, which is fortified by the landing gear. The landing gear absorbs the forces imposed on the aircraft by takeoffs and landings. Any maneuver that causes acceleration or deceleration during flight increases the forces and stresses on the wings and fuselage. Stresses that act on the wings, fuselage and landing gears are tension, compression, bending, shear and torsion. The stres...

Egg remains an interesting and inexpensive protein source of the diet over two millennium years because of its nutritional and multifunctional properties. From the point of view of nutrition, egg is one of the complete food items, since it is rich in protein, amino acids, vitamin and most of mineral substances. Egg proteins have highest protein efficiency ratio, biological value and net protein utilization (Hoffman and Falvo, 2004). Egg can be used as a binding agent, a gelling agent, an emulsifier, a foaming agent and a coloring agent in food industry (Cook and Briggs, 1986; Watkins, 1995; Caner and Cansiz, 2007; Jaekel et al., 2008). There were 6.4 billion egg laying hens in the world and 1,182 billion eggs were produced
The battle on what to consume has been debated since the Stone Age. Through those times and leading into modern day, it starts at sunrise. Eggs are normally the “go to” food that society correlates with breakfast. A person can choose raw, boiled or fried eggs. The healthy benefits and implications from consumption of each one of these cooking styles are the variables in question. Eggs have the potential to be more than just another breakfast item. The right balance of preparation and consumption can satisfy a person’s hunger while providing nutrients effectively to the body. The egg has an excellent balance of proteins and vitamins that are essential for muscle development and stamina and therefore contribute to an overall healthy diet.
