Introduction In this lab we had to design a system that would test if changing the mass‚ angle of release and length would have any effect on the period of a pendulum. Hypothesis As the length‚ mass and angle of release change‚ the period (T) will change for each one of these factors.

The Inverted Pendulum is inherently unstable‚ higher order multi-variable and highly coupled system which can be treated as typical non-linear control problem. [1] This is the benchmark for designing‚ testing‚ evaluating and comparing of different classical and contemporary control methods. The control of IP has been a research interest in the field of control engineering because it is the most difficult system being an inherently unstable and highly nonlinear. So this system became a choice of dynamic

How a Pendulum Works Isaac Olson Mitch Koebnick‚ Kyle Orr 13 September 2013 A Period Purpose There are three purposes of this experiment. The first purpose is to determine the relationship of the period and the amplitude of the pendulum. The second purpose is to determine the relationship of the period and the mass of the pendulum. The final‚ but most certainly not the least‚ purpose of this experiment is to determine the relationship of the period and the length of the pendulum. Procedure

Physics (from Ancient Greek: φυσική (ἐπιστήμη) phusikḗ (epistḗmē) “knowledge of nature”‚ from φύσις phúsis "nature"[1][2][3]) is the natural science that involves the study of matter[4] and its motion through space and time‚ along with related concepts such as energy and force.[5] More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves.[a][6][7] Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy

In Poe’s story the “The Pit and the Pendulum” he distinctively uses symbolism‚ repetition‚ mood and diction to tell a tale of hope over circumstance to make this story come to life for the reader. Unlike the hypersensitive characters from other stories‚ such as the narrator in “The Tell-Tale Heart‚” this narrator claims to lose the capacity of sensation during the swoon upon receiving his death sentence that opens the story. This story is different from Poe’s other works such as this narrator remains

The Pit and the Pendulum Analysis Essay Edgar Allan Poe’s "The Pit and the Pendulum" takes place during the Spanish Inquisition. The morbid short story consist on an innocent man’s fears coming to life after he is sentenced to death. "The Pit and the Pendulum" showcases the theme of terror and cruelty by developing descriptive setting‚ intense plot‚ and creative irony. Setting is a major part of the thesis because it captures the readers attention to see what the character sees. One of the

PCS125 Lab – The Simple Pendulum Objective and Background Objective: The Objective of this experiment is to examine the simple harmonic motion and to determine the value of the acceleration due to gravity from the analysis of the period of the simple pendulum. [1] Background: There are three equations that will be used to calculate the period of motion of the simple pendulum. They are the slope of the line of the graph of T² against L‚ and the gravity of the pendulum motion. The period of the

The Pit and the Pendulum by Edgar Allen Poe‚ and The Lowest Animal by Mark Twain have many differences but one central theme. They both express the belief that the human race can be destructive. Both stories have very different settings. Poe’s story The Pit and the Pendulum takes place in a completely pitch black room. From lines 102 - 103 the narrator says‚ “the blackness of eternal night encompassed me”(pg.252). The narrator wakes up and tries to navigate and almost falls in a pit. He was put

Q1. Outline the historical development of the models of the universe from the time of Aristotle to the time of Newton. Aristotle: Geocentric model of the universe involved a series of 56 concentric spheres to which celestial objects were attached. The Earth was not in motion as the stars showed no measureable parallax. Each planet‚ the Sun‚ and the Moon were in their own sphere and the stars were positioned on a larger sphere surrounding all the others. Ptolemy: Geocentric model of the universe
