02TTB204 Mechanics of Solids Part B Lab Buckling of Struts 1. Introduction The task was given to obtain the buckling stresses for pin-ended steel struts of various slenderness ratios and compare with theoretical predictions obtained using the Euler and Rankine-Gordon equations. 2. Theory The method of obtaining the buckling stresses followed was to use data show in Appendix A. From the record of applied load‚ P‚ against deflection‚ δ‚ a Southwell plot of δ against

Properties and changes are used to describe matter. A property is a trait of matter‚ when that sample of matter is in a fixed state. There are two different types of properties: physical properties and chemical properties. A change is something that alters the properties of a substance. There are two types of changes: chemical changes and physical changes. A physical property is a property that can be observed without changing the makeup (or composition) of a substance. Some examples of a physical

We then were required to run a series of anion and cation tests to determine the composition of the unknown solutions. To get more knowledge about these solutions we ran a series of dilutions to see if

we are discussing separations of a mixture that contains pure substances‚ it all depends on whether you can separate the substances by physical means. That means‚ utilizing each substances physical properties such as boiling point‚ melting point‚ and magnetism. Separation of a Mixture of Solids Lab Report Assistant To begin this experiment I got out me scale and little plastic dish and the mixture of substances

Title: Physical and Chemical Properties Purpose: To investigate the physical and chemical properties of pure substances as distinguishing characteristics. Procedure: 1. Set up a well plate with 24 pieces and fill two with either Dilute HCl or Dilute NaOH. 2. Set up four test tubes with any single substance in each one. 3. Observe and record original color and odor of substance. 4. Light flame with matches. -Hold test tube with substance in it over flame with clamps -Observe and record

AMERICAN INTERCONTINENTAL UNIVERSITY SUBJECT: Municipal Solid Waste Descriptions and Problems ABSTRACT: The Municipal Solid Waste is based in 4 main components that are recycling‚ composting‚ landfilling and waste-to-energy that is mainly done by burning the waste. This is known as materials of no longer being of value and is thrown out for disposal. Waste is handled and separated into different containers which are divided into solids‚ plastics and paper mainly. There are different types of

Rate of Evaporation of Different Liquids Objective of the Project This project is of the rate of evaporation of different liquid‚ in which we also discuss the factors which affect the rate of liquid. Introduction When liquid is placed in an open vessel. It slowly escapes into gaseous phase ventually leaving the vessel empty. This phenomenon is known as vaporization or evaporation. Evaporation of liquids can be explained in the terms of kinetic molecular model although there
