- Three materials X, Y, and Z are available for a certain usage. Any material selected must have a good weldability. Tensile strength, stiffness, stability and fatigue strength are required with fatigue strength considered being the most important and stiffness the least important of these factors. The three materials are rated as follows in these factors. Properties X Y Weldability Excellent Рoor Good Tensile strength G E Fair Stiffness Very Good G G Stability G E G Fatigue strength F G E Which material should be selected? Explain your choice.arrow_forwardA cylindrical rod with a diameter of 15.24 mm and a gauge length of 400 mm is subjected to a tensile load. If the rod is to experience neither plastic deformation nor an elongation of more than 0.45 mm when the applied load is 31000 N, which of the four metals or alloys listed below are possible candi- dates?

- 1.19 A brass alloy has a yield strength of 280 MPa, a tensile strength of 390 MPa, and an elastic modulus of 105 GPa. A cylindrical specimen of this alloy 12.7 mm in diameter and 250 mm long is stressed in tension and found to elongate 7.6 mm. On the basis of the information given, is it possible to compute the magnitude of the load that is necessary to produce this change in length? If so, calculate the load. If not, explain why.arrow_forwardThe frame of a space shuttle type vehicle must have a high yield strength and high stillness, and the most important design factor is weight. Of all the materials presented in this chapter, what material might be the most suitable for the frame of a space shuttle? Assume that there will be both tensile and compressive stresses. For a space shuttle, cost is not a limiting factor. (a) You can eliminate entire classes of materials from consideration with a brief statement about their unsuitability. (b) What material has the highest specific yield strength? Give the yield strength, specific gravity, specific yield strength, elastic modulus, and specific elastic modulus for this material. (c) What material has the highest specific elastic modulus? Give the yield strength, specific gravity, specific yield strength, elastic modulus, and specific elastic modulus for this material. (d) Compare the materials with the highest specific yield strength and highest specific elastic modulus for suitability in the space shuttle frame. (C) Discuss the suitability of the top-rated material for this design from the viewpoint of the ability to produce a frame.arrow_forwardA brass alloy has a yield strength of 280 MPa, a tensile strength of 390 MPa,and an elastic modulus of 105 GPa.
