The assembly shown below with M8x1.25 bolt/nut is subjected to an oscillating force F that changes between 0 and Fmax. Obtain the Fmax (in kN) with a saftey factor of 3, such that the amplitude of the alternating stress on the threaded section of the bolt does not exceed 46 MPa. Assume that the bolt and nut were preloaded sufficiently. The stiffness of the clamped material is evaluated as 963 MN/m and the stiffness of the bolt is calculated as 334 MN/m.
