Martin Luther King s Letter From Birmingham Jail

Dr. Martin Luther King, one of the most influential men in the world, had played a pivotal role during the Civil Rights movement.

As he discussed these broad discussions, King managed to use rhetorical devices throughout his letter, as well as establish different modes of persuasion. King negated the clergyman s critiques by saying that he was compelled to spread the word of freedom to others. He applied pathos to gain an anticipated emotional response from the clergyman, stating a biblical metaphor about the Apostle Paul leaving his village to carry the gospel of Christ throughout the world.

Martin Luther King addresses this method of resistance in his text, â€Å"Letter from Birmingham Jail†. Martin Luther King Jr personally drafted the text as a response to criticisms made in a statement by clergymen whom apposed King’s nonviolent methods of resistance to continuous issues of racism occurring in Birmingham, Alabama. As expressed by King and described in his text, civil disobedience should meet certain criteria to be considered so. One of these criteria is that the law being disobeyed should be unjust. Also, according to King, this direct action should be non-violent, as this was the basis of his teachings. Furthermore, the individual should be aware of consequences, and willingly accept them as he/she performs this act of civil disobedience. Finally, there must be no alternative to this act, meaning that some form of protest must have been attempted in the past, to no avail. Consequently, the only alternative would be to break the unjust law at hand. Martin Luther King executed this form of action in his efforts to challenge racism in Birmingham Alabama. Similarly, famous fighter Muhammad Ali used the same tactic in order to achieve justice decades later. Muhammad Ali bravely refused to be drafted during the Vietnam war because of his religious beliefs and was therefore convicted of violating the selective service laws.Show MoreRelatedMartin Luther King s Letter From Birmingham Jail1690 Words   |  7 Pages1960’s were a time of civil disobedience and protest against the inequalities in America.

It is because each works produces different merchandise and different machine. In order to accomplish energy salvaging step, it is of import to cognize the fabrication procedure and it energy ingestion in the procedure. Cenpak Holding ( M ) Sdn Bhd The company produces expandible polystyrene boxes and corrugated box. The production of corrugated box based on the client specification. The production procedure is begins with starch readying and paper axial rotations. The following phase is corrugators subdivision. In this subdivision, the corrugator machine will convey together a sheet of paper to organize individual or dual bed corrugated paper. The paper is produced in a uninterrupted procedure harmonizing to the merchandise design and specifications. The machine is divided into chief subdivisions, flute and hot home base subdivisions. The flute subdivision is divided into flutes portion and dual angel. The paper axial rotations are transported under the axial rotation stands utilizing conveyers. The operator so feeds the axial rotations into the corrugators. In the individual facer, the paper is which give the paper the fluted form. Starch is applied to the tips of the flutes on one side and the interior line drive is glued to the flute. The corrugated flute medium with one line drive attached to it, is called individual phaser web and travels along the machine towards dual angel. This subdivision is known as line preheater. There, the individual facer web meets the outer line drive and forms the corrugated board. After the board emerges from dual angel, it passes a steam heated a steam flatcar known as hot home base, the cutter cuts the board to the exact required length to obtain the corrugated sheet. Finally, corrugated sheets are stacked and sent to the 2nd subdivision of the corrugators hall by operators. Then, the corrugated carton box goes to following procedure which is publishing and slotting, cutting, turn uping and pasting the board to fabricate a corrugated box. In this subdivision, it have flexographic or flexo machines. This machine will publish, cuts, creases and glues the board into the concluding form in one operation. Unfortunately, non all operation can be managing with flexo machine. For the big poster board or more sophisticated packaging manner instance, it will travel to decease cutting and sewing or pasting procedure manually. Last, the corrugated carton box will be sent to review subdivision. In this subdivision, the merchandise will be inspects whether it is fulfill the client specification or non. After the review subdivision is complete, the merchandise will be sent to the client. Flow Diagram of corrugated box procedure Starch Preparation Paper Rolls Corrugator Printing Die Cut Gluing/Stitching Inspection Delivery The 2nd of merchandise in this company is expandible polystyrene boxes.

Compressed air is chiefly needed for the control of the molding procedure, purge of H2O and gap of the mold. Vacuum is required in the chilling and emptying of extra steam before the mold gap. Genting Sanyen Industrial Paper Sdn Bhd Flow diagram of production procedure of paper Waste Paper Raw stuff Storage Stock Preparation Paper Machine Whitewater Preparation Wire Section Imperativeness Section Dryer Section Completing Section Paper Rolls First, the waste paper is collected and some waste paper is import from another company. After that, the natural stuff will be store up to six-month supply. The stock readying starts with the cleansing procedure. It starts with the centrifugal cleansing of the diluted mixture of contaminated fibres. The diluted waste paper mixture is pumped to different machines whose intent it is to divide the useable fibres from the ink or any other soiled stuff, which might be attached to the fibre. The mixture has to be farther diluted, dewatered, washed and pressed to hold those fibres reclaimed, which are clean and transcend a certain fibre size, the remainder is discarded as sludge. The fibres are separated in short and long fibres to command the strength and quality of the paper by choosing the appropriate mixture in the paper production subsequently on. Then, the procedure continues to the paper machine subdivision. The paper machine is used as a large drier which transform the loose fibres into solid sheet of paper. The paper machine can be spliting into another subdivision which is the white water readying system, the wire subdivision, the imperativeness subdivision, the drier subdivision with size imperativeness and finishing subdivision. Whitewater readying is provides the circulating H2O for the paper machine. The wire subdivision is orientating the fibres on a traveling screen ( wire ) and allows large measures of H2O to go through through. The imperativeness subdivision presses the H2O in the imperativeness felt which in bend is cleaned with hard-hitting H2O noses and suction tubings for H2O remotion. For the drier subdivision it will distilling inside the cylinder and heats the surface to about 140 A ; deg ; C. Lastly, the finishing subdivision provides a steel calendar for smoothing the surface.

Determination of Gravitational Acceleration

Question: Discuss about theDetermination of Gravitational Acceleration. Answer: Introduction Historical and Theoretical Basis behind the Determination of Gravitational Acceleration Aristotle, the great Greek philosopher, believed that every motion or effect has a cause. The downward movement of heavy earthly elements is related to their nature which makes them to move downwards towards the center of the earth. Similarly, light objects are caused by their nature to move upwards to the inner spheres of the moon. In other words, Aristotle believed that heavy objects do not move towards center of the earth because of external force of gravity but rather because of their heaviness. However, Brahmagupta (an Indian mathematician and astronomer) held that because of the spherical shape of the earth, it attracts objects towards its center. Disputing Aristotle, Galileo discovered that all objects accelerate equally when falling. His findings were based on the assumption that if air resistance is negligible, all objects are assumed to fall at the same acceleration (Garg Kalimullah, Arun Lima, 2007). In the same century, Robert Hooke suggested that there is a force of gra vity that inversely varies with the square of their distances. Later, Kepler came up with three laws that govern the orbital movement of planets. His first law states that all planets move in an ellipse with the sun at one focal point, balanced from the center. Secondly, objects near the sun move faster than those farther away. And lastly, the planets distance from the sun determines the time it takes to revolve around the sun. Based on Keplers laws on the motion of planets, Isaac Newton sought to investigate the motion of all objects. He discovered that all falling objects follow the same principles as outlined in Keplers Laws. Apart from the laws of motion, Newton also suggested that all matter exerts a force called gravity that pulls matter towards its center and this force is dependent on the mass of the object and also wanes with distance. For instance, the Sun has higher gravity than the earth and the earth has more gravity than an apple. Newtons Law of gravity explains the earths movement around the sun. Ideally, the earth would move straight throughout the universe. However, this is not the case because the sun exerts its pull on the earth that forces the planet to move in elliptical orbit. Newtons theory on gravity has made it possible to explain the rise and fall of the ocean waters that occurs because earths gravitational pull on the moon. The force of gravity is responsible for the shape and structure of the earth. It is one of the fundamental parameters in physics that governs the motion of objects on the surface of the earth. In simple terms, earths gravity can be defined as the force with which the earth attracts objects towards its centers. It is also the rate at which a falling object increases in speed as it falls. A free falling object is able to move with a specific value of acceleration, known as gravitational acceleration and is denoted by letter g. Theoretically, this value was determined by Newton to be 9.8m/s. There are several ways that has been used by physicists to measure the acceleration due to gravity. Some of these ways have produce errors that compromise the final results. Recently, there have been new developments on the instruments used for measuring gravitational acceleration. The objective of these new developments is to reduce the errors that are common with scientific experiments (Cook 1957, pp. 34). According to Newtons principle, gravitational acceleration can be determined by computing the time t for a falling object through a given vertical distance by using the formula Y= ut +1/2gt2. .... .. . .. . . . .. . .. . .1 Where u= initial velocity of the object at the start of timing. If the objects falls from a stationary point then u=o and the equation reduces to y =1/2gt2 . . . . . . . . . . . . . . .. . . . . . . . . . . . . . . . . . . . . . . . . . . 2 In such experiments that involve free fall objects, determining the accurate time for the flight is a major challenge since there is no precise means of measuring the start time as one hold a stop watch on one hand and watching the falling object. As a result, the scale and clock does not provide the precision required in this experiments. Application of electronic devices seems to have solved the problem of timing. With electronic timer, the correct start and stop times can be obtained thus increasing accuracy and precision. In simple terms, Newtons law on force stipulates that force on an object depends on its mass and acceleration. In other words, force is a product of mass and acceleration (F = ma). Thus, for an object to experience acceleration, a force has to be applied to it. This is what Newtons Universal law of gravity states. The general formula as set by Isaac Newton for determining the force between two objects is given by F = GM1M2/ r2 . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 Where G= gravitational constant M1 and M2 are the masses of the two objects, r = the distance between the two objects. In other words, force between two objects is obtained by multiplying the product of their masses with a constant, G and dividing by the square of the distance between them.

This equation was first determined by Galileo upon dropping cannonballs of different masses and realizing that they landed at the same time. His explanation was based on the fact that they experienced the same acceleration (acceleration due to gravity). Similarly, when a coin and a feather are both dropped simultaneously in a vacuum where there is no air resistance they land together. Overall, determining acceleration due to gravity we measure the time of travel from a stationary point and the distance travelled as shown in equation 2. Second Section Objective: To determine acceleration due to gravity using three different methods; ticker tape timing, stroboscopic analysis, and electronic timing. First Method: Ticker Tape Timing In this experiment, a length of ticker-tape is threaded in a ticker timer and attached to a trolley at one end. The trolley is pulled by a constant force along the bench. The elastic cord is looped on one end around a rod which is attached to the trolley. To keep the force constant, the cord is stretched by the same amount of force with which the trolley is pulled. The experiment is repeated several to improve on precision. This method is limited in accuracy because of friction of the tape as it passes through the ticker timer which reduces the rate of acceleration. This can be reduced by using larger mass but it also needs investigation. Results The experiment was done three times per student in the group. The timer runs at 50 dots per second. Thus, the period was 0.02s. Tape Number Initial position Final position Results (m/s2) 1 0.015 0.066 7.1875 2 0.0145 0.068 7.4306 3 0.02 0.082 7.75 Second method: Stroboscopic Analysis A camera was set up on a tripod directly in front of the stand with the electromagnet at the top of the frame. The position of the camera was adjusted appropriately so that at least one meter of fall was photographed. The strobe light was positioned so that the falling object would be illuminated from the side. With the apparatus fully set the flash rate of the strobe was adjusted to 25 flashes per second. After connecting the electromagnet to a power supply, the voltage was adjusted to hold the ball bearing. With the room lights off, the Camera aperture was opened wide to give a sharp view through viewfinder As the strobe light flashes, the cable release is depressed to open the shutter, the ball bearing was released by switching off the power supply. The shutter is then closed when the ball bearing finishes the fall. Results Trial C(m/s2) g(m/s2) 1 4.798 9.596 2 4.899 9.798 3 4.903 9.806 4 4.910 9.820 Third method: Electronic Timing The stand was set with electromagnet and then connected to power supply The voltage of the power supply was adjusted so that it held the steel strip vertically. At the base of the strip, the light beam was mounted just below where it could interrupt the beam (the adjustment is done cautiously so as not to interfere with initial velocity) The timer was reset to zero and the steel strip released by switching off the power supply to the electromagnet and timing recorded The experiment was repeated 4 times and each time results recorded The length of the strip was measured with much focus on accuracy Distance s (metres) Time(1/2t2) g 2.00 0.209 9.789 1.8 0.183 9.810 1.6 0.163 9.815 1.4 0.143 9.859 1.2 0.122 9.802 1.0 0.102 9.803 Discussion When using the ticker timer method, we noticed a few errors. First, the timer would start before the ball enter free fall causing smaller long elapse in time and subsequent low values of g. Secondly, the tape was not in parallel with the floor which caused a random deviation in elapse time. As a result, the value of g was way below the theoretical value. However, with a photogate the precision was highly increased with value nearing the theoretical value. In trial 4, the value was slightly higher possibly because the ball was dropped at an angle that reduced the distance, hence the high value. The electronic timer is the best of the three methods in precision since it provides a percentage error of 0.0009% Conclusion From experimental values, it is evident that gravitational acceleration is a constant since it depends on constant values. This support the preposition of Galileo that cannonballs of different masses falls at the same rate since they experienced the same acceleration (acceleration due to gravity). Similarly, when a coin and a feather are dropped in a vacuum where there is no air resistance they land together. This implies that determining acceleration due to gravity we measure the time of travel from a stationary point and the distance travelled which requires accuracy and precision in the instruments. Some errors noted in the values resulted from instruments. Reference List Bell, H 1916 A New Method for Determining G The Acceleration Due To Gravity. American Meteorological Society.
