data is collected in the sense of Applied Load (N) vs. Displacement (mm). Average Applied Load and Displacement from all five specimens is then used to calculate the Stress (MPa) and Strain. Stress/Strain graph is then plotted in order to find the Yield Point (YP) and Ultimate Tensile Stress (UTS) by visual inspection of the graph. Young’s Modulus is then found by dividing Stress by Strain in the elastic region. 0‚002 Strain is located on the Strain axis of the graph and

bonds: the par value(F)‚ the maturity(n) the yield to maturity(y)‚ the coupon interest(CF)‚ the interest payment frequency(m)‚ and the interest rates for each period(ri). We assume that the coupon interest is fixed‚ then the price of bonds(P)is the discounted cash flows of each period: P=i=1nm(CF(1+ym)i)+F(1+ym)mn=i=1nm(CF(1+rim)i)+F(1+rnm)mn Indeed‚ to intuitively understand this equation is not easy. Firstly‚ we can see that the yield to maturity(y) is a kind of “average” of the interest

Unit 2 PPA 1 Complexometric Determination of Nickel using EDTA Introduction: The Aim of the experiment is to determine the percentage of nickel salt using a complexometric technique. Ethylenediaminetetraacetic acid (EDTA) is a hexadentate ligand which forms stable complexes with most metal ions‚ thus is widely used to determine metals in complexometric titrations. EDTA can be represented as H4Y and in alkaline conditions‚ it exists as Y+ ions: The Y4- ions form 1:1 complexes with metal ions

O2 and C3H8 were combined‚ how many moles CO2 will be produced? Which is the excess reagent? How much excess reagent will be left unreacted? Calculate the theoretical yield‚ potassium chloride produced from the reaction of 2.56 g of K and 3.85 g Cl2. If an actual experiment produces 3.81 g KCl‚ calculate the percentage yield.

steel mills around the world. The purpose of roll bonding is to combine two materials through rolling in order to achieve the desired mechanical properties. This report intends to explore the evolution of the mechanical properties such as ductility‚ yield strength‚ ultimate tensile strength and hardness through grain refinement at the microstructural level. The mechanism of surface deformation‚ grain boundary deformation and reduction of work hardening is further analysed. This report also makes an

9-19-13 Dehydrating and Rehydrating a Hydrate Introduction The mass percent of water was determined using the mass of water and dividing it by the total mass of the hydrate and then multiplying that answer by 100%. The number of moles of water in a hydrate was determined by taking the mass of the water released and dividing it by the molar mass of water. The number of moles of water and the number of moles of the hydrate was used to calculate the ratio of moles of water to moles of the sample
