Principles of Metal Manufacturing Processes - Lab Report ExampleThe present research has identified that when more loads are applied the specimen breaks at the centre. The data of load versus extension of the specimen is collected and used in slowness of stress and strain. The values are plotted on an X-Y graph and yield a typical graph. From the graph several material properties could be careful and observe. The pursuit experiment investigates the spring chickens Modulus of a piece of fit out subjected to tension. To get the Youngs Modulus, stress and strain of the wire must be calculated from the recorded results. The linear section of the graph is referred to as the yield strength where the material shows elastic behavior and it is used in the calculation of E. On the otherwise hand, the other part of the graph is referred to as the non linear section. The yield point is the transition between the linear and the non-linear sections, and the magnitude of stress at this secti on is termed as the yield strength (Y). The slope of the linear section of the curve gives the materials Youngs modulus, given in GPa. The formula for calculating Youngs modulus is shown below. The slope of the linear section of the curve gives the materials Youngs modulus, given in GPa. The formula for calculating Youngs modulus is shown below. The objective of this experiment is to determine the Youngs Modulus when a piece of wire is subjected to varying forces. Apparatus The following apparatus were used during the experiment 1 x G-clamp, approximately 10 cm jaw 1 x 2 wooden blocks 1 x single pulley placed on a bench clamp 1 x meter rule 1 x Adhesive tape 2 x cardboard bridges 1 x mass hanger with 8 slotted masses, 100g each 2 x lengths of copper wire 1 x safety spectacles Wire rolls and threads Procedure The experiment set up was as shown in figure 3 below. Figure 3 Experimental setup 1. After the set up was made, a copper wire was stretched and located horizontally along the bench as shown in figure 3 above 2. A maker was made from the adhesive tape and it was attached to the wire to make it less 2 m from the clamp and approximately 5 cm from the pulley. The marker was set to line up with the meter rule so that it could be used to measure the extension of the wire. A loop was made in the end of the wire for loading 3. The original length of the wire was measurable and recorded. This was the length from the clamp to the marker. A small mass of 100g was then placed to stretch the wire and the length recorded. 4. The masses were increased gradually in stairs of 200g while the force and the corresponding extension was recorded in each case.
