Introduction: The objective for the lab was to determine properties of materials by using a tension test. The properties that were determined was Young’s Modulus, ultimate tensile strength, and yield strength. Three aluminum alloys were tested. The first was the AA 2024 , which is high strength used in aerospace applications. The second specimen was AA 5052, which had low strength, but high ductility.
Various materials used for manufacturing a chain link are steel, stainless steel, carbon steel, alloys etc. The chain link which we have considered is used for hoisting purposes, this is because the oval shape is ideal for crane hook as the depth of the crane hook is greater than the width. We will study stresses induced in the link. It is necessary to study the stress distribution, deformation and deflection so as to avoid design failure and loss. The necessary information required for the project like material properties, type of load to be applied, intensity of load is taken from the textbook ‘Strength of Materials ’ by Dr. R. K. Bansal.
k called the “spring constant” is the variable we are trying to find as well is the total of the stress made on the object. Stress is the force on unit areas in a material that develops a result in externally applied force. The reason why k must be multiplied by two is because modern versions of the slingshot are designed to have a Y-shaped handle with two rubber straps and a pouch attached to the points. Since I pull the rubber band back to increase its displacement both individual strand is parallel producing the same spring constant. F would be measured the same since it would be calculated from both spring constants.
To recognize the most straightforward course to grow high caliber in Al alloys from pieces of assembling businesses. 2. To evaluate the effect of machining parameters i.e. cutting speed, cutting angle and depth of cut on microstructure, mechanical and tribology properties. 3.

Projective external loads are assumed to be the maximum external forces that can occur in the pontoon bridge. For researchers to analyze mechanics of material, they must have a better understanding of physical and natural science (physics), analysis of load on a body in a state of equilibrium, mathematics, and laboratory skills which also includes computer
Ferricyanide; A Cyclic Voltammetry analysis Analytical Lab 1: 2410 L Name: Austin Stevens Lab Partners: 3:05-5:55 Group 2 Date: 10/12/15 Introduction: This Experiment was done to determine the concentration of an unknown, the half-wave potential, and to the determine the calibration curve of the reduction of ferricyanide to ferrocyanide through the use of cyclic voltammetry1: Fe(CN)63- + e- ↔ Fe(CN)64- Cyclic voltammetry uses the knowledge of voltammetry; which is the measure of a typical current response caused by an electrical current which is captured on an electrode and then measured, to determine potentials2. Cyclic voltammetry is one major proponent of voltammetry. Cyclic voltammetry
This supports my hypothesis, where I predicted this proportionality. From Newton’s Second Law F=ma, I derived an equation isolating a: a= (1/m)F - (1/m)fric. I solved the equation for the line of best fit, and used the y-intercept to figure out the friction, which was the only remaining unknown in the equation. Once the friction was known, I was then able to plug in measured values and verify my hypothesis. I proved with this equation, using examples from my data, that the force is in fact directly proportional to
Measuring Glass 8. Funnel 9. Measuring Cylinder HYPOTHESIS If the independent variable changes then the results and outcomes of each testing done with the insulators will be different. The time intervals will also depend on which insulator is the best, as it can affect the structure of the material and how it conducts its temperature(s). If steel wool is made of fine strands of steel, and steel is a form of metal, metal is known to be a good conductor of heat because of the close packing of the metal ions in the lattice and the delocalised electrons that can carry kinetic energy through the lattice.
For this the mold should be made from high strength preferably of hardened steel. Secondly, for better mechanical properties it is advised that the molded items be annealed. Thirdly, mold release agents if required should only be made from fluorine based compounds to avoid stress cracks. Applications Poly (ether sulphone) has a variety of applications in a vast array of fields. The most successful applications are mentioned below.
