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?
