A cylindrical 2014-T6 aluminum alloy bar is subjected to compression-tension stress cycling along its axis, results of these tests are shown in Animated Figure 8.20. If the bar diameter is 10 mm, calculate the maximum allowable load amplitude (in N) to ensure that fatigue failure will not occur at 1.0 x10' cycles. Assume a factor of safety of 2.9, data in Animated Figure 8.20 were taken for reversed axial tesion-compression tests, and that S is stress amplitude. FE N [The...

An engineering company is designing and testing a car suspension system. The system has a conventional suspension design, consisting of a shock-absorber and spring at each wheel. The shock-absorber provides a damping effect that is proportional to the vertical speed (i.e. up and down motion) of the wheel, and the spring's resistance is proportional to the vertical displacement of the wheel. The design team analyses the suspension system in two separate parts: Part 1 - dynamics of the spring-damper system;...
