Lab 2 Report for MATSE 473 Determining Molecular Weight using Solution Viscosity Name: Mengfang Li Group D Lab Partners: Michael Lorenzo‚ Peter Mcclure 01/24/2012 Introduction: This lab was designed to demonstrate the method to measure the intrinsic viscosity of the prepared polystyrene. Intrinsic viscosity‚ which is measured from the flow time of a solution through a simple glass capillary‚ has considerable historical importance for establishing the very existence of polymer molecules

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

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. Materials Lab stand Protractor Cardboard Fishing line Stopwatch Weights Hook for weights Tape Ruler Weighing scale Logger Pro Variables Independent Angle of release Dependent Period Length

Any object that fall to the earth have a constant acceleration due to gravity of -9.80 m/s^2 if air resistance is ignored. If an object is small and have a reasonable mass‚ we can predict the final velocity of the object and the time of fall‚ since smaller objects with smaller mass have less air resistance. Objects with smaller masses have less air resistance because their velocities are smaller. Objects with larger masses‚ on the other hand‚ will have more air resistance because their velocities

Free-Fall Acceleration Introduction Galileo Galilei (1564-1642)‚ the man first accredited with the correct notion of free-fall with uniform acceleration‚ stated that ’if one were to remove entirely the resistance of the medium‚ all materials would descend with equal speed.’ Today‚ this statement holds true for all objects in free-fall near the Earth’s surface. The purpose of this experiment is to verify Galileo’s assertion that acceleration is constant. In addition‚ the magnitude of acceleration will

In a world without gravity‚ one would be weightless‚ but always nauseous. Because of this‚ it would be very difficult to complete a lot of your daily activities without throwing up. If you tried to eat something while you and your food are floating around‚ you will probably have a lot of trouble trying to hold your food down. In 0-g‚ life would be very hard. Roller coasters are a perfect example of this. I do not do well on roller coasters. I get sick when I encounter zero gravity for that split second

Literary Analysis of “Gravity” by David Leavitt The following pages will consist of a literary analysis of the short story presented by the author David Leavitt‚ which is taken from his book “A Place I’ve Never Been” (Nguyen‚ 2006). “Gravity” narrates the story of a boy with AIDS‚ whose life is slowly consuming like the wax of a lit candle. The author presents the reader with the crudity of enduring such disease mainly from the patient’s and his mother’s perspective. The underlying intention

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
