The bolt is a 5.8 class metric grade, with a proof strength of 380 MPa. The joint is intended to be permanent. Determine a suitable length for the bolt, rounded up to the nearest standard size in millimeters. Calculate the bolt stiffness, the elongation of the bolt after the necessary preload is developed, and the bolt torque required to apply the preload.
