Effect of Body Mass and Cord distance on bungee electric cord heap Jump MotionThe physics idler bungee cord rebelTo what extent a remainss mass and continuance of the electric pile affect the bungee cord bulgeing relocation?Dhouha KhammassiAbstractThis essay investigates a luggage com tripments question during a bungee jump in order to answer the question To what extent a bodys mass and aloofness of the cord affect the bungee cord jumping proceeding? the investigation takes place with comparing three diametrical bungee stack s performance in two simulation laboratory examineations. The prototypal is to check the intercourse between the bungee jumping cord and its relation to Hookes fairness and finding its elastic limit. The second is to inspect the motion in terms of velocity and acceleration changes with varying the weight of the body affiliated to the cord and changing the length of the cord, since they ar the factors to be considered in the research que stion.IntroductionScope of workThe vine jumpers of Pentecost Island in Vanuatu inspired the federal agency of Bungee jumping, as it was viewed by way of a rite of passing play to manhood. It is ab show up jumping from a amply point such(prenominal)(prenominal) as a bridge, a building or a crane attached to nylon braided, rubber shock cord. It is from a fixed structure most of the duration but it is possible to do it from an intent floating in the air, for example, a moving crane or a hot air balloon. It became a popular lark the last two decades in the United States of the States where multitude do it for the sake of the excitement and adrenaline pumping sensations. Of course this sport involves a lot of risk and most of the accidents occurring argon from miscalculations in the length of the elastic cord, which leads to many an(prenominal) horrifying accident when people end up landing on the sur spirit or the cord collapses, it occurred to my mind that exploring such a occu rrence might be very interesting.ObjectiveIn this essay I aim to look at the physics behind Bungee Jumping. The aim of this essay is to investigate the factors affecting the bungee jump motion. I entrust be exploring the stages that the bungee jump goes through and the factors affecting it furnishing a safe landing but exciting at the very(prenominal) time. This involves data record from laboratory investigates and graphing data with analysis. Exploring this matter fuck comfortably make connections between fundamental concepts of physics and real world phenomena Bungee Jumping. Therefore attempting to answer, To what extent a bodys mass and length of the cord affect the Bungee jumping motion?Back grounds cultivationSafety of Bungee jumpingThere is no doubt that a thrilling from a height usually more than forty-five meters carries its receive risk and can be very dangerous, Bungee jumping is alike(p) most adrenaline pumping sports, when done wrong, can be hazardous and fi fty-fifty lethal.Bungee jumping mishaps can occur because of faulty equipment or disregardless of safety dance steps, the injuries that could have been avoided are human errors when the body strapping fails out-of-pocket to improper attachment or flawed predominate, Chris Thomas is an example of this atrocious incident, he died during a charity jump in Swansea, Wales because of his weight1. Another role is cord length miscalculation and the jumper ends up hitting the ground or the bungee cord just snapped, similarly to what happened to Erin Langworthy, an Australian char who almost drowned with her feet tied together in Zambezi River at Victoria Falls2. In 1989, this activity was banned in France and one state in Australia afterward three people faced their death3. And many other incidents ca employ people to collapse on concrete and suffer from extreme cranial wound or even die because the rope was too long, that actually happened to Matthew E. Coleman4, who died at an Adv enture World bungee jump.However, unavoidable injuries might occur, minor injuries such as skin burn, which is triggered through gripping the cord, happen when Bungee jumpers do not act accordingly to the guidelines given. Some of them stated that they got slapped in the face by the cord.Other mores serious injuries such as eyesight prostitute or temporary retina haemorrhage5, strokes and traumatic carotid artery dissection happened to fit and hale youth.But injury inflicted by the cord, such as choking to asphyxiation, appears not to happen. This can be explained by a combination of factors, including the cords borderline torsional stiffness. Also, the minor pendulum motion keeps the cord from contacting the jumper and tangling or strangling him,No modern-day jump site has seen any serious entanglement, and it is noteworthy that many participants enjoy somersaulting during the free fall without any harm or disaster occurring.Principle components in the physics of Bungee jumpingT o allow the bungee jumping motion to occur the person jumps from a high surface and the cord stretches as he is moving downwards, this demonstrates the cords elasticity, which can be defined as the ability of a body or the cord, in this case, to oppose a outcome exerted on it and change tempt and size and to return to its equivalent characteristics when the strain is re come upond.The law of elasticity, Hookes law, heady by Robert Hooke, an English scientist in 1660, which states that, for relatively small contortions of an object, the displacement or size of the extension is directly proportional to the deforming reap applied.Under these conditions the object returns to its original shape and size upon removal of the load.If the force exerted exceeds a certain amount, cognise as the elastic limit, it would create a permanent deformation to the body even when there is no force applied on the body. The elastic limit differs from a body to another because both of the resistan ce to stress and it depends on what the body is made of. Elastic materials expand hyperfine and thinner until rupturing at their breaking point.The strength of materials is the measurement of a bodys capacity to bear strain and stress. Stress is the internal force applied by a segment of an elastic body upon the connecting part and strain is the dimensions deformation ca utilize by stress. Elastic materials are the materials whose stress disappears after the exerted force is removed.In bungee jumping the cord is subjected to pull, this is identified as tension. When the cord has weight attached and it is being pushed, this is know as a compressive stress. During the jump, the external forces twist the body around an axis, it is known as the torsional stress.Experiment 1 Hookes LawThis experiment is carried out to calculate the elasticity of the bungee cord and its elastic limit.VariablesIndependent variablesThe force exerted on the bungee cord subject variableThe extension of the c ord due to the force appliedControl variableThe aforesaid(prenominal) bungee cord used for different weightsShape of the weight used bloom of the cord from the groundApparatus UsedSince the Hookes law experiment apparatus is usually equipped with a retort remain firm, which is a stand that has a ruler and a pointer attached to the spring, but since I am using a bungee cord instead of the spring, I used a regular clamp and I had seven different masses labeled 0.1 kg, a digital measuring scale with 0.01 kg uncertainty, three different car bungee cords purchased at the local anaesthetic hardware shop, a ruler0.0005m and a flat surface to perform the experiment on. modeFirst of all, I measure the length of the car bungee cord is provided with two nobbles at distributively of the extremities, therefore I hang the cord with one hook on the clamp, I measure the weight holder then I hang it to the bottom hook line the I add one weight cylinder, afterwards I carefully measure the length of the cord. Next I measure each weight on the scale and I measure the extension on the cord each time the weight is added. All the measurements are enter during the experiment.Experiment 2 Bungee Jumping SimulationVariablesIndependent variablesLength of the cordThickness of the cordForce applied to the cordDependent variableTime taken to complete a bungee jumpVelocity of the bodyAcceleration of the bodyControl variableThe same bungee cord used for different weightsShape of the weight used, using the same set of weightsHeight of the weights from the motion detector, it is controlled by placing the Vernier motion sensor on a laboratory chair with the ability to move it around and adjust its height.Apparatus UsedVernier motion sensor connected to a computer with a data logging software6 installed which will be crucial for more accurate timing and graphing purposes than manual timing. Also, the same Bungee cords used in the previous Hookes law experiment are used since characteristic s are already measured and this experiment is relating to the previous one, a meter ruler can be used to insure that the apparatus is perpendicular to the motion sensor. Blu-tack and tape is also needed.MethodA clamp is put on a flat surface, to stop it from falling I and the bungee cord is hung from it with the weight holder hang at the bottom of the cord, both of the hooks attached to both ends of the cord are secured with Blu-Tack to prevent the apparatus from falling and act as the harness in this simulation. The Vernier motion sensor is put on the laboratory chair, and before starting the experiment, activate the motion sensor and oscillate the cord with the suspended weight holder to test the sensitivity of data logging and test the range of motion detection. Afterwards the weight is elevated to the source of the cord and it is released with minimum to no force. This step is repeated by adding weights and the weights are secured with a thin strip of tape to avoid them falli ng off. end pointBibliographyAussie Plunges into Raging Waters after Bungy Cord Snaps.
