The figure shows a section of a large coupling. Each bolt in this joint is subjected to cyclic load fluctuating between 0 and 13 kN. The members are made from steel. The members have equal thicknesses and total length of members is L=37 mm. Each bolt is initially tightened carefully to 78% of proof load. The bolt is to be Metric grade 5.8 M12x1.75 (coarse-pitch series). The threads has been manufactured by rolling and reliability for bolts is 95%. Calculate the stiffness of the bolt (in kN/mm).

RB&W11 recommends turn-of-nut from snug fit to preload as follows: 1/3 turn for bolt grips of 1-4 diameters, 1/2 turn for bolt grips 4-8 diameters, and 2/3 turn for grips of 8-12 diameters. These recommendations are for structural steel fabrication (permanent joints), producing preloads of 100 percent of proof strength and beyond. Machinery fabricators with fatigue loadings and possible joint disassembly have much smaller turns-of-nut. The RB&W recommendation enters the nonlinear plastic deformation zone. The figure shows a cross section of a grade 25 cast-iron pressure vessel, with a torque factor K of 0.09. Use Eq. (8-27) to estimate the torque necessary to establish the desired preload given that preload F;= 14.4 kip, bolt stiffness kb = 5.21 x 106 lbf/in, number of threads N=11, and material stiffness km = 8.95 × 106 lbf/in. in-11 UNCX 2 in grade 5 finished hex head bolt in in 162 No. 25 CI Determine the torque necessary to establish the desired preload and the turn of the nut in…

Torque in = 40nm Holding torque out = 896nm 8.Using your answers from the gear box above, and given that the input shaft has a diameter of 12 mm and the output shaft has a diameter of 15 mm, both shafts are made from aluminium. When this transmission system was operated, it failed. Identify the position where the failure occurred and the reason for this failure. Suggests improvements to the system to overcome the failure mode. The shear strength of aluminium is 207 MPa.
