Solved in 2 steps
- A); How to determine the yield point for materials that do not exhibit a well defined yield point? Name some of such materials. B); Whatis allowable load/stress. Give two different equations that determine the allowable load/stress.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 importantWhat is meaning of elasticity?
- Which choice below best describes the mechanical property of materials called toughness? a. Ability to compress without permanent deformation b. Ability to bend in the elastic range c. How much energy a material can absorb without breaking d. Indentation resistanceQ3) A- What is fatigue strength?.The criteria for selecting a material for Aircraft is high strength and less weight. The material to be selected is Select one: Mild Steel Cast Iron Ceramic Aluminium Alloy
