You are an engineer working on a project and your prototype has failed prematurely. You question whether or not a key component of the prototype was manufactured with the correct material. There are two way to check for the material properties. The first way is to have a material certification done to confirm the exact material composition. This will take some time. The second method to confirm the material properties is to make an ASTM test sample and test for the material properties. This tensile test was completed on a test sample with an initial diameter of .501” and an initial length of 2”. The Load-Deflection data for this tensile test is below. Use this data to answer the first set of questions on the Final Exam in eLearning. A. Determine the Ultimate Tensile Strength B. Determine the 0.2% Offset Yield Strength C. Determine the value of the Proportional Limit D. Determine the Modulus of Elasticity E. Determine the Strain at Yield F. Calculate %…
