turesRule of Mixtures Composite stiffness can be predicted using a micro-mechanics approach termed the rule of mixtures. Assumptions 1. 2. 3. 4. 5. 6. Fibers are uniformly distributed throughout the matrix. Perfect bonding between fibers and matrix. Matrix is free of voids. Applied loads are either parallel or normal to the fiber direction. Lamina is initially in a stress-free state (no residual stresses). Fiber and matrix behave as linearly elastic materials. Longitudinal Modulus Equal strain

3. Why are stabilisation salts added to evaporated or condensed milks prior to heating? The heat stability of milk is of tremendous importance in the successful processing of milk and the manufacture of most dairy products. Appropriate application of heat becomes necessary not just for destruction of spore-resistant micro-organisms but also for the preservation of the most desirable product characteristics. However‚ milk should not coagulate on heating. Heat coagulation is chiefly caused by de-stabilization

Debate Given the carbon costs the Athabasca Tar sands should not be allowed to continue production. Not only will the cost rise when there is little oil left but the tar sands also create a lot of pollution. If they are not careful the cost is going to get outrageously high because they will eventually have to pay for some of the damage they cause with all the pollution they make. If they continue it will ruin the environment around the oil sands and they will hurt the environment in many other

Types of Mixtures Lab Purpose • To classify types of mixtures • To determine the polarity of substances Background Information: Polarity In the middle of the night of March 24‚ 1989‚ the giant oil tanker Exxon Valdez veered out of the shipping lanes in Alaska’s Prince William Sound and struck a reef. The side of the tanker was ripped open‚ and 11 million gallons of crude oil flowed out into Alaska’s clear blue waters. Because petroleum oil is insoluble (does not dissolve) in water and less

Robert Lawrence and Edmund Stephens‚ two graduate students of geology from Columbia University‚ organized the Saline Salt Company in 1974. Keeping in mind the fact that every 1‚000 grams of seawater contains approximately 35 grams of various salts‚ the two men pictured limitless wealth for them by extracting these salts. Common table salt comprises 27 grams out of each 35 grams and is easy to extract; so‚ the men decided to begin producing it. They picked New Iberia‚ Louisiana as the ideal location

Requirement…………………………10 Procedure……………………….….11 Observation…………………………12 Conclusion………………………….13 Introduction: Metals and alloys undergo rusting and corrosion. The process by which some metals when exposed to atmospheric condition i.e.‚ moist air‚ carbon dioxide form undesirable compounds on the surface is known as corrosion‚ The compounds formed are usually oxides . Rusting is also a type of corrosion but the term is restricted to iron or products made from it .Iron is easily prone to rusting making its surface rough

and solid C were both extracted from unknown solution by first using chemically active liquid-liquid extract‚ followed by vacuum filtration. Liquid C and solid C were then purified with the use of simple distillation and recrystallization respectively. Through the process of recrystallization‚ the percentage purity of solid C was found to be 6.01%. The melting point range of purified solid C was 117.0 – 119.0C while the boiling point of liquid C was found to be 117C. The identity of solid C and

A carboxylic acid is an organic acid characterized by the presence of at least one carboxyl group. The general formula of a carboxylic acid is R-COOH‚ where R is some monovalent functional group. A carboxyl group (or carboxy) is a functional group consisting of a carbonyl (RR’C=O) and a hydroxyl (R-O-H)‚ which has the formula -C(=O)OH‚ usually written as -COOH or -CO2H. Carboxylic acids are Brønsted-Lowry acids because they are proton (H+) donors. They are the most common type of organic acid. Among

Conclusion As previously discussed throughout our report Red Stone is currently facing many issues within their company‚ they are unable to deliver their finishing projects on time and remain on budget. A number of gaps have been identified; these gaps have been that cause of all the issues. By determining where the gaps are we are able to act efficiently and effectively to complete all projects successfully and on or before the due date of the project. After analyzing the survey data and compiling

Catnip Catnip is a perennial herb found growing wild throughout native to Europe and southwestern to central Asia where it is thought to have originated. The leaves are heart-shaped‚ toothed‚ opposite and covered with fine downy hairs especially on the under sides giving the whole plant a grayish green appearance. They have an aromatic mint-like flavor Chervil although many people may not be familiar with chervil‚ it has been around for a long time. Aristophanes‚ a playwright of Ancient
