One flange is attached to four 5x8 grade and M16 bolt connections with a total preload force of 80,000 N Calculate the factor of the bolt
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.
Problem 3: A Hexagonal bolt connects two members. The joint has a gap 1 = 2 in and the applied
load is 2000 lb. Both of the clamped parts are steel. A preload of 90% the bolt's proof
strength will be applied first. For this design, an SAE grade 1, 5/16"-18 UNC-2A bolt
is chosen made from A307 with rolled threads. Washers are included between the head
and the joint, and between the nut and the joint. Determine a suitable length for the
bolt? Find its safety factor against yielding and against joint separation. Are these
values acceptable?
