1.2 Objectives and Aims
The main objective is to recover energy from track’s Vibrations for Safety and Monitoring using Aurdino controller which will Improve Rail-Road Accidents. The proposed harvester is designed to power major areas where there is no proper maintance of electricity. The different equipments usually need a power supply of 10-100 Watts, for example generating warning signals, switches and health monitoring systems.
1.3 Literature Review
The first step taken in this project was to do research on a variety of subjects to gather the information required to be capable of designing the harvester. The main area of study was to gather information about harvesters and further just in detail research on Energy

As shown in figure, there are frictional losses due to the meshing of gears and misalignment of the shaft when load is exerted on the track.
The proposed mechanical motion rectifier harvester system consists of two major parts. The first part is input assembly, which acts to convert bi-directional linear motion into single directional rotational motion. The input assembly consists of two rack and pinions, and two roller clutches. The roller clutches are fitted into the two pinions, either of them engage input shaft at a single direction.
The second part consists of the gearhead, power generator, and flywheel. These components are use to convert the motion into useful energy. Figure 2.1: Flow Chart The harvester will be mounted to and spans two rail ties. As it is shown in Figure, the harvester consists of : two rack and two pinion gear which convert the linear motion to rotatry motion. Figure 2.2: Modified Prototype
A bearing clutch will be used to rectify the up-and-down motion of the rail track and a gearbox will be used to amplify the rotatry motion and a permanent magnet DC generator will be used to convert that rotation into usefull energy(electricity). When the train travels over the track, the rail-tie system displaces vertically. The rack gear is fixed in the subgrade, the harvester travels up and down relative to the rack gear, and the pinion gear moves relative to the rack gear. Thus a small amount of linear motion is converted to
Neither Timber Terror nor Tremors has an engine or anything pushing the cars along the track. The only time the cars are aided by a machine is when the car is being carried to the top of the first hill and the compression brakes at the end, but from then on, the cars are in the hands of potential energy and kinetic energy (“Roller Coaster”). Mechanical energy is used to lift the train cars to the top of the hill. Once it reaches the top of the hill, the car has a very large amount of potential energy. After the car reaches the top and begins its descent, it loses potential energy with the loss of height and gains kinetic energy. Each time the coaster goes up a hill, it loses kinetic energy and gains potential energy (“Energy Transformation”). Although potential and kinetic energy play the largest roles in the physics behind a
How the Case Arrived to Supreme Court: Dollree Mapp was a female employee in an illegal corporation run by a Cleveland kingpin Shon Birns. The police were informed of a possible possession of illegal material in relation to her place of work within her residence. The police thoroughly searched the property and discovered the illegal material along with the fact that she was allowing Shon refuge in her basement. However, they did so without a warrant. Dollree was sentenced one to seven years in prison. Mapp appealed her case to the Supreme Court stating the evidence that sentenced her was not found with probable cause.
In his book Jean Gimpel goes over medieval primary industry, which includes energy sources like the creation of mills that were moved by wind power or by water. In these cases, the turning of the wheels were used to drive the shafts that were connected to the gears used to operate the entire machinery. The agriculture revolution includes the creation of the plow. The plow was considered to be very important. It had existed
In this case we need to overcome the friction force from the axles, and tires to be able to power the vehicle by mousetraps far enough. There is a coefficient of friction between the axle and the bearing where the axle sits in the bearings and does not spin together so that is where most of the friction is created. The front wheels currently are hard rubber, and the rear wheels are currently cutting disks which are a hard material and very skinny, creating a very little amount of friction. The total force of friction would need to be less than the force of the mousetraps on the axle throughout the traps angular travel. Methods that were used to reduce friction consists of using lubrication on the axles to make it easier to spin, use skinnier wheels to reduce friction from the ground, and making the vehicle lighter with a simpler design. (See APPENDIX 1 for detailed
r centuries farming had been down with manual labor and animals. Beginning in the early 1800’s steam powered engines and other mechanical devices began to be used in agriculture and farming. John Froehlich helped make permanent changes to farming with his invention of the ‘traction engine’.
it is not on the rail it reduces friction which is why the train can reach such high speeds.
At the Bottom of the loop Fs is acting upwards against gravity told hold the train on the track. So Fs = Fg +

When you start moving that's when the motor lets go then you have kinetic energy when it falls it builds up enough energy to propel the rest of the ride. Even though you don't notice or think about it gravity is the reason you stay on the track.
A rightward moving rider gradually becomes an upward moving rider, then a leftward moving rider, then a downward moving rider, before finally becoming a rightward-moving rider once again. There is a continuing change in the direction of the rider as he/she will moves through the clothoid loop. A change in direction is one thing of an accelerating object. The rider also changes speed. As the rider begins to climb upward the loop, he/she begins to slow down. What we talked about suggests that an increase in height results in a decrease in kinetic energy and speed and a decrease in height results in an increase in kinetic energy and speed. So the rider experiences the greatest speeds at the bottom of the loop. The change in speed as the rider moves through the loop is the second part of acceleration which the riders experiences. A rider who moves through a circular loop with a constant speed, the acceleration is centripetal and towards the center of the circle. In this case of a rider moving through a noncircular loop at non-constant speed, the acceleration of the rider has two components. There is a component which is directed towards the center of the circle (ac) and relates itself to the direction change and the other component is directed tangent (at) to the track and relates itself to the car's change in speed. This tangential component would be
The purpose of this project was to use parts salvaged from the deconstruction project to build a new machine that could complete a task. Two choices were presented as the task: option one was to lift an object of undetermined weight up to a height of twenty to sixty centimeters, and then deliver that object to a platform twenty centimeters in height; option two was to launch a tennis ball sized object through a goal post one to two feet in height. After analyzing our available materials, we opted for option one. We measured success in this task by our device’s ability to lift and deposit that object, as per the requirements of the task.
In the poem “To Paint a Water Lily” by Ted Hughes, the speaker conveys his attitude toward nature as perplexing, complex, and deceiving. He also expresses his opinion of the artist and the difficulties brought on by him trying to paint and recreate not only the picture of a water lily and its natural scene, but also capture the intense environment that is both peaceful and full of constant activity. The author achieves this through literary techniques such as: imagery and juxtaposition.
The physics that goes into the construction of a roller coaster is a fascinating, complex process that many don’t understand. When the ride begins, you can usually hear chains being pulled. These chains are pulled by a motor which lifts the train of cars to the top of the first, and tallest hill. Once on the top of the hill, gravity takes over and no motors are needed. This is because while going up the first hill, the cars were able
Many young and married couples are frustrated because people are constantly asking them about when they are going to get married and have a baby. Matt and Abby also felt that frustration. Because they were so tired of people asking them about when they were going to have a baby, they decided to adopt one.
