Hardness Tests and Charpy Impact Test Objectives: 1) To compare the hardness between mild steel‚ carbon steel through Vickers Hardness Test. 2) To compare the hardness between High Quality Carbon Steel and ASSAB steel through Rockwell Hardness Test. 3) To compare the hardness between carbon steel and mild steel through Brinell Hardness Test. 4) To study the differences between mild steel and carbon steel upon Charpy Impact Test. Introduction: Hardness is a measure of the resistance

The theory that best applies to my behavior change‚ is the self determination theory. The self determination theory looks at motivation and personality and combines aspects of behavioral self regulation as well as personality development (Ryan & Deci‚ 2000). It takes into account the psychological needs of the person‚ and also looks at a combination of these factors in order to determine the type of motivation a person has. According to Ryan and Deci‚ there are three needs that need to be met for

Amber Crisp 3/5/14 3/5/14 Flame Test Purpose In this experiment I will learn how to perform and observe the flame tests of some alkali and alkaline earth metals and be able to identify and unknown chemical by the color of the flame Procedure I placed about 0.5 mL of 8 different chemicals into 8 different places in the 24-well plate. I then lit the handy wick to keep a flame burning. I soaked a cotton swab in the first chemical and moved the cotton swab in and out of the flame rapidly to see the flame

Lab #2 Determination of Density Britney Williams Chemistry 121 Dr. Yu 1/29/13 Purpose: To determine the densities of aluminum and zinc cylinders Density is the relationship between the mass of an object and its volume. Sometimes density can be easy to sense. If two objects have exactly the same shape and size‚ the denser one may feel heavier. If their densities are close together‚ it can be hard to tell the difference. It gets really tough if you are dealing with materials that have very different

Determination of pKa James McDuffie ABSTRACT: In this lab‚ the pKa of unknown solution #4 was measured Introduction: This lab focused on the equilibrium constant‚ Ka. Ka is associated with chemical properties of acids. The equivalence point will be reached once the moles of OH- equal the moles of HA and once this point is reached‚ the PH changes very quickly. With the results‚ a titration curve should be produced. Experimental Section Materials and Methods: A buret with NaOH solution

Tittle: Determination of moisture Objectives: 1. To determine the moisture content of selected food samples using drying oven method 2. To determine the moisture content of selected food samples using moisture analyzer. Introduction: Moisture content is one of the most commonly measured properties of food materials. The choice of an analytical procedure for a particular application depends on the nature of the food being analyzed and the reason the information is needed. In this experiment

TITLE Hardness Tests And Charpy Impact Test OBJECTIVE 1. To compare the hardness of the carbon steel‚ mild steel and ASSAB steel using three different hardness tests‚ which are Vickers Hardness Test‚ Rockwell Hardness Test and Brinell Hardness Test. 2. To study the hardness of mild steel‚ carbon steel and ASSAB which is an important in engineering to design structures or components that related in mechanical properties 3. To determine the resistance of carbon steel and mild steel

The micro-hardness test can measure the case to core depth parts. Micro-hardness testing is required where the superficial hardness test is not conceivable due to material’s small geometrical shape. The welded part we were going to examine‚ experienced the similar criteria since the welded bead of the joint was way too small. To test the hardness of our welded area we had gone through a micro-hardness test using a Shimadzu micro-vicker hardness testing machine. In the following
