Q6. (a) Three identical fatigue specimens (denoted A, B and C) are fabricated from a non-ferrous alloy. Each is subjected to one of the maximum- minimum stress cycles listed in Table 26 (the frequency is the same for all tests) Table 26 Specimen Omax (MPa) Omin (MPa) A +450 -150 +300 -300 +500 -200 Rank the three specimens in terms of their fatigue lifetimes (highest to lowest). Justify this ranking [5 marks] (b) A cylindrical tie rod of diameter 20...

As shown in Figure 8, the structural member (beam) is 7m long, carries a 2 kN point load, a 1.2 kN/m uniformly distributed load and is supported at points A and B. The beam is constructed from two pieces of steel plate (2 at 80mm x 8mm) that are welded together with 3mm welds. Section properties for the beam are also listed. Given the support reactions as RAv 5.8 kN and RBv 2.2 kN, as well as the shear force...
A 3 m rigid bar AB is supported with a vertical translational spring at A and a pin at B The bar is subjected to a linearly varying distributed load with maximum intensity g Calculate the vertical deformation of the spring if the spring constant is 700 kN/m. (ans: 21.43 mm) 2. A steel cable with a nominal diameter of 25 mm is used in a construction yard to lift a bridge section weighing 38 kN. The cable has an...
