3. An M16 x 2 bolt with a slotted hex nut is used to clamp together two 25 mm steel plates. The joint is assembled with a size 16 N washer underneath the bolt head. 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. Assume that coefficients of friction between the bolt, nut, and collar are all ~0.15. For steel, use E = 207 GPa. Standard threaded fastener lengths, dimensions of hexagonal nuts, and dimensions of metric plain washers are provided in the textbook appendices.
