Where Men Win Glory by Jon Krakauer - Essay Example According to the author, Tillman was an ambitious, driven and complex individual who decided to enlist in the US Armed forces despite his lucrative May 2002 $3.6 million NFL contract offer. The September 11 terror attack on the US influenced this decision. While serving on his second tour in Afghanistan, Tillman died while trying to save members of his platoon. Initially, army officials informed his family that his death occurred during crossfire between the platoon and enemy combatants. This information was soon negated by investigations done after the army revealed that a ranger within the Tillman’s platoon shot him. Through Tillman’s story, Krakaeur hoped to shed light on real, behind the scenes experiences of men and war. The public viewed Tillman as a national hero for his selfless decision to enlist in spite of his lucrative contract. Tillman was at the peak of his American Football career when he joined the army. The Cardinals team had offered him a $ 3.6 million, three-year contract, an offer that would cater for all his financial needs and keep him out of harm’s way. On the contrary, enlisting into the army would result in adverse physiological and psychological consequences. The US was recovering from the September 11 terrorist attack, which exposed weaknesses in the country’s counterintelligence mechanisms and sparked a full-fledged war against countries in the Middle East. Choosing to enlist during this time meant that Tillman would be in the frontlines fighting for his life sooner compared to those who enlisted during peaceful times. The country’s former President George W. Bush capitalized on Tillman’s decision to join the army. He used Tillman as a poster-boy to encourage other citizens to enlist and serve their country. Even in death, Tillman proved that he was a national hero. He died in the line of duty in spite of the marred

Principles of Metal Manufacturing Processes Lab Report

Principles of Metal Manufacturing Processes - Lab Report Example The 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 calculation 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 calculated and observe. The following experiment investigates the Young’s Modulus of a piece of wire subjected to tension. To get the Young’s 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 other 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 section is termed as the yield strength (ÏÆ'Y). The slope of the li near section of the curve gives the material’s Young’s modulus, given in GPa. The formula for calculating Young's modulus is shown below. Â  The slope of the linear section of the curve gives the material’s Young’s modulus, given in GPa. The formula for calculating Young's modulus is shown below. The objective of this experiment is to determine the Young’s 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 fixed 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 measured 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 steps of 200g while the force and the corresponding extension was recorded in each case.
