Alloy Metal Briefly describe the steps that are used to ascertain whether a particular metal alloy is suitable for use in an automobile valve spring. Explain how the tensile strength and fatigue strength of a particular metal affect the materials selection process for an automobile valve spring. For a steel alloy material in a helical […]
What is fatigue strength (i.e. S in the Figure above) in [MPa] at the cycles calculated in (a) for this aluminium alloy. Determine the total number of cycles during the time .
A 2014-T6 aluminum rod (3.5 cm in diameter) is subjected to a repeated tension-compression load cycling along its axis at a frequency of 100 Hz. If the part must last approximately 278 hours before failure, calculate the maximum allowable load amplitude (in N). 400 300 200 tr, 0 103 — – 1045 steel — — […]
