Q1/A List some of the material usage changes that you have observed over a period of time in some manufactured products. What reasons can you give for the changes that have occurred? B) Why is it important or helpful to classify materials into different groups as we have done in this course?

MENG222 Strength of Materials Please please I'm begging you help me in this problem Need to include sample calculations, solved. Tabulate/mention the given data and what is supposed to be obtained and how. All thank and appreciation ?? ?

I belongs to mechanical engineering field please give answer according it   Could you elaborate on the concept of stress and strain in materials engineering? Discuss how these properties are measured, the differences between various types of stress and strain, and provide examples of how this knowledge is crucial in designing structures to ensure safety and reliability."

Show the typical Stress versus Strain curve for the following materials, and define the materials properties "The stress-strain curve can be used to read off the structural load ability of materials. For many materials, including metals, their loading bearing capability is one of the most important material properties". by reference to the diagram: a) Hammer head is made from hardened tool steel b) Smelter is made from refractory ceramic c) Cable is made from pure copper d) Box is made from polypropylene

In your summer internship, you are tasked with measuring the ultimate tensile strength of a material to determine if it meets your company’s (Superior Super Ships Inc) specification. Your boss is worried that the new low-cost supplier, Shoddy Alloys Inc, may not be reliable but it is the only way to source on-time the SS304 needed to make finishings for Jeff Bezos’ new yacht, the Black Pearl. You collect several load versus displacement curves, as illustrated below. The initial diameter of the round gauge section is 0.25 in. You also collect the instantaneous diameter of the specimen during the test using a laser. Using the provided data, calculate what is the ultimate tensile strength measured in this test?

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.
