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 …show more content…
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
First, for any experiment the idea and the method of running are very important to plan. The first idea that our team came up with was the parachute. The idea was vetoed due to the fact that the same object (parachute) could not be repeated in another medium, thus it is not possible to get higher mark. Next, and the most frequently used idea, is the drag measurement on the free falling body in various types of mediums. The experiment was deemed simple, yet it was not obvious how to measure the time when the velocity comes to terminal. Or does it ever come? Then, the next idea was pendulum, as it is a simple machine and we instantly thought up the idea to use hair dryer, and intentionally to measure the velocity of the flow an anemometer was suggested.
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
Margaret Atwood's “Bluebeard's Egg” is a story centred upon a woman called Sally, describing her relationship with her husband, Ed, and her best friend, Marylynn. The story is told in a third person perspective, a “God-like” figure that takes us through the whole narration, but only revealing the thoughts of one character, Sally. In the story “Bluebeard's Egg”, the main conflict is within the protagonist, Sally; that is, her external self versus her internal self. Sally's external self does not act according to her internal self. In other words, Sally does not express her emotions and thoughts due to the many concerns that she has, both psychological and environmental.
In order to produce this experiment, you began by setting up the angles at which the spring gun would launch the metal ball onto the ground to measure its distance. The spring gun was placed, ideally, at table
There are many forces that play into an object falling down and hitting the ground. For a fragile object like an egg, making it survive a small fall is very difficult let alone four stories. It is possible to make the egg survive however, by encasing it in something. You can compare the egg to a human in a car. A car crash can be deadly however the car that is around acts like the objects you would encase an egg in. In a car crash, or in most collisions, there is a primary and a secondary impact. The primary impact in a car crash would be the car deforming and being destroyed due crashing into something. The secondary impact is the contents in the car moving, in this case, quite violently. In many cases, the secondary impact might actually be more deadly than the primary, and the same goes for an egg drop, because there are contents inside the
While you watch a person swing, place your hand at the maximum point of the swing’s achieved height and then count how many seconds it takes to return back to that same height. You have just measured the period of the swing. The period of the swing is the time it takes the swing to make one full move back and forth. The equation used to solve for the period mathematically is T = 2p (square root of L/g), where L is the length of the pendulum, and g is gravity. There are a few things that can change the period of a pendulum. As length increases and as the force of gravity increases so will the period. Likewise, when both gravity and length of the chains decrease, the period does also. My reference Mark Nethercott says that if there are no outside influences, the period stays constant at about 15 degrees of arch, but the amplitude must be low. This statement corresponds with Newton’s first law of motion (law of inertia) that says, “Every object remains at rest or in motion in a straight line at constant speed unless acted on by an unbalanced force.” (Physics, A World View p.31).
T = 2π√(L/g)), where T is the period of the pendulum, L is its length and g is the acceleration of gravity.[1]
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...
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.
Introduction: I chose to investigate this topic out of pure curiosity to see how the length of a pendulum affects its period of motion. A pendulum is a suspended point of mass, hung from a fixed point on an inextensible cord. When it is pulled and released from one side of its equilibrium, at x°, the pendulum swings back and forth on a vertical plane under the influence of gravity (La Né Powers, 2006). The motion is periodic and oscillatory; I am determining the oscillation or otherwise known as the period of motion (Resnick & Malliday, 1977, pp. 310-311). The period of motion is the amount of time taken to swing back and forth once, measured in seconds and symbolised by T (Kurtus, 2010). Galileo discovered pendulums and he found that the period of motion is proportional to the square root of the length - T∝√l (Morgan, 1995).
A pendulum is an object hanging from a fixed point with a mass that swings back and forth under the influence of gravity. Sometimes this mass is called a bob, as it bobs up and down as it swings side to side. Pendulums are acted upon by three main forces: gravity, tension, and air resistance. While gravity always pulls down on the bob, tension pulls upward towards the pivot point for the string on the rod, or where the string pivots. However, both the amount and the direction of the pendulum’s tension changes as it swings. When the pendulum swings left of its equilibrium position, or the place where the pendulum comes to rest, gravity is still acting downward, but the tension is acting towards the pivot point, so it
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.
In 1797 the Frenchman Andre Jacques Garnerin performed the first parachute plunge from an aircraft using a basket below an open parachute, which was made of silk and solidified with supporting poles (The History of Sport Parachuting). When the first parachute was dropped, physicists didn’t have a wealth of knowledge about the physics that supported skydiving. Ever since the first drop, skydiving has been an evolving sport, as this is due to the developing knowledge of physics. Skydiving is perceived as a very risky sport in the eyes of the public; therefore, in order for the sport to continue, physicists needed to discover ways to reduce the risks involved. They were successful in doing this by developing better equipment and techniques. The economical impact of skydiving has been huge. The research involved in the design of the chute, the materials used, and the engineering invo...
A pendulum is described as a point mass suspended by a string of negligible mass. Typically, it rests in its equilibrium position, but once displaced, the point mass will begin to swing back and forth, about its fixed position. The motion repeats regularly, and the period can be predicted. The model T=2π√(L/g) predicts the period if the pendulum, where L is the length of the string. According to this formula, the amount of displacement plays no role in the length of time an oscillation takes. But how is that possible? Experiments have shown that with any angle of the pendulum less than or equal to 90 degrees from rest position, it in fact holds up. Of course, the pendulum will stop eventually due to outside forces, such as wind resistance and
But vibrations can also be beneficial. For instance, many different types of mining operations rely on sifting vibrations through which different sized particles are sorted using vibrations. In nature, vibrations are also used by all kinds of different species in their daily lives. Orb web spiders, for example, use vibrations in their webs to detect the presence of flies and other insects as they struggle after being captured in the web for food. The reason that mechanical systems vibrate freely is because energy is exchanged between the system’s inertial (masses) elements and elastic (springs) elements. Free vibrations usually cease after a certain length of time because damping elements in systems dissipate energy as it is converted back-and-forth between kinetic energy and potential energy. The role of mechanical vibration analysis should be to use mathematical tools for modeling and predicting potential vibration problems and solutions, which are usually not obvious in preliminary engineering designs. If problems can be predicted, then designs can be modified to mitigate vibration problems before systems are manufactured. Vibrations can also be intentionally introduced into designs to take advantage of benefits of relative mechanical motion and to resonate systems (e.g., scanning microscopy). Unfortunately, knowledge of vibrations in preliminary mechanical designs is rarely considered essential, so many vibration studies are carried out only after systems are manufactured. In these cases, vibration problems must be addressed using passive or active design modifications. Sometimes a design modification may be as simple as a thickness change in a vibrating panel; added thickness tends to push the resonant
