Experiment Title: Torsion Vibration. Introduction : Torsion is the twisting of a metallic rod shaped object‚ when a torque is applied on two sides’ perpendicular to the radius of a uniform cross-sectional bar. Objective : Determining the natural frequency of a system undergoing tortional vibration. Theory : Using Newton’s second law of tortional system. ( [pic] ………………….

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

Chem 105 Guide to the Formal Laboratory Report The purpose of a formal report is to communicate effectively to another person the goal‚ procedure‚ data analysis method‚ and results of your laboratory work. The report is divided into several well-defined sections. Each section must be present in a complete report. To earn an outcome point for the laboratory report‚ a student must submit a formal lab report that earns a score of at least 90/100. Each error (factual‚ grammatical‚ typographical

The Uniform Crime Report (UCR) from the FBI is the most widely cited crime report. It is used for comparison with victim surveys and self-reports. It came about in 1930 when the Department of Justice compiled and published national crime statistics. It was the major source for United States crime sets until 1974. Most information in the media is usually based on the UCR‚ although it is not properly reported. The UCR involves voluntary participation from local police departments who report the

This experimental value for gravity agrees well with and is within one standard deviation of the accepted value for this location. I. INTRODUCTION The study of the motion of the simple pendulum provided valuable insights into the gravitational force acting on the students at the University of Utah. The experiment was of value since the gravitational force is one all people continuously experience and the collection
