Quiz Set 1 f23

Several applications are listed below. Determine the relative importance of resilience and toughness of the materials chosen for each application. Sort the items based on whethere resilience is most important, toughness is most important, or both are equally important

None

Yield strength, ultimate tensile strength, linear coefficient of thermal expansion, modulus of elasticity (E), proportional limit, and rupture strength are all examples of mechanical properties of engineering materials. O True False A non-destructive test is any examination of an object in any manner which will not impair the future usefulness of the object. Non-destructive tests include: magnetic-particle, impacting testing, radiography, eddy current, and fluorescent-penetrant. O True O False One way to make a metal stronger is to increase the metal's grain size. O True O False --- OL T A metal that has a crystalline structure is called amorphous. O True O False

For material SAE 4130 WQT 1300, please obtain its ultimate strength: s u =__________ ksi. Use textbook only, write down where you take the value(s), then submit your handwriting solutions later.

Need help starting this assignment.  1- Determine the maximum normal stress, the maximum shear stress, the Modulus of Elasticity, the maximum bending moment and the maximum stress due to bending (also known as flexure stress) on the material, from the information provided. 2- From the results of your analysis, determine what material was used for this test. Check whether the material can withstand the different types of loading the hip implant experiences. Use a factor of safety of 4.

Pls help ASAP

Select All the correct statements from below.  a. If the averaged distance between partial dislocations for material A observed under TEM is smaller than material B, the estimated stacking fault energy of material A is lower than material B. b. K_IC is a material property that doesn't change with testing conditions c. The main difference between high cycle fatigue and low cycle fatigue is the difference in the number of cycles to failure d. A negative R value in fatigue test indicate the minimum stress is compressive in nature
