Using the figure from Question 2, imagine the lamp gets heavier and heavier until one of the cables breaks. If all of the cables have the same tensile strength, a) which one will break first, and b) why will that one specifically break first? You do not need to provide Given, Assume, and Problem Type/Features for this question. You just need to provide Find, Analyses and a Conclusion. Provide an explanation for b) that isclear, concise, correct and well organized. Use at least one diagram (2D or 3D) to make your case as to why one of them will break before the others. You can use equations/math to support your explanation as well, if you want, but expressing your answer in words and using logic will be all that is necessary. Youranswer to a) i.e. which one will break first, can be your “Conclusion” to Question 3

Project 2: You have been asked to obtain an object/structure/component that has failed (It may come from your home, workshop, an automobile repair shop, a machine shop, and so on) and conduct an investigation to determine the cause and type of failure (i.e. simple fracture, fatigue, creep). What are the working and environmental conditions that causes the failure? In addition, propose measures that can be taken to prevent future incidents of this type of failure. After you have determined the failure type of your case study, your leader asked you to write shortly about the other mechanisms of failure.

In the First project: you have been asked to perform tensile testing for four different materialsand analyse the results and work on some NDT process selection:a. For the results shown in Table 1 of the tensile testing that you have performed, find thefollowing, if you know that the original length of specimen is 20.8 mm and the original diameteris 6.4 mm. Fill the calculated results in the summary table below (Table 1):1. Plot the engineering stress versus engineering strain for each material and L-D Diagram.2. Compute the modulus of elasticity, E in GPa.3. Determine the yield strength at a strain offset of 0.002.4. Determine the tensile strength in MPa.5. What is the approximate %El ductility, measured by percent elongation?6. Compute the modulus of resilience.7. Determine the fracture stress in MPa.8. Compute the final area (Af) in mm2.

6- Discussion: 1. Sketch a diagram for the experimental instrumentation, devices. 2. State any possible error source in the experiment. 3. State any suggestions to improve the experiment or another way the estimate the specific heat of solid materials. 4. Compare the exact value with that obtained experimentally. alaa Hameed Faisal Page (2/2)

Check the correct statements. a) The huge differences between the values ​​of theoretical strength and real strength of the crystals were attributed to the existence of punctual defects like gaps. b) The extremely high strength limit of filament crystals (whiskers) is generally attributed to the low degree of internal and surface imperfection and justifies their use as reinforcements in composite materials. c) Transmission electron microscopy, decoration technique, special X-ray techniques and indentation allow experimental observation of disagreements. d) During plastic deformation, there is an increase in the density of dislocations in a crystal. The formation of unevenness loops, irregularity in the grain boundaries, deposition of thin films and formation of solid solutions are among the different sources of unevenness multiplication.

What would be the specific heat of sample 1? The block’s initial temperature is 98 degrees C

Q1/ A 2 kg of specimen has a ratio of 90 and 10 % wt (Pb and Sn alloy, respectively) is heated to 260° C and at the same temperature it is entirely a-phase solid solution. The alloy is melted to be liquid in a ratio of 50% while the rest is a-phase. This is achieved by either heating or replacement the alloy composition at a constant temperature. a- What is the temperature must be the sample heated? b- How much tin must be added to the sample (2 kg) at 260 °C to get this state?
