Problem 1 (10 points): The stiffness values for the bolt and members shown

in Figure are 13.32 M lbf/in and 8.09 M lbf/in respectively. The bolted tension

joint is loaded by a force cycling between 4 and 6 kips. All bolts have been

carefully preloaded to Fi = 25 kip each.

1. Determine the yielding factor of

safety.

2. Determine the overload factor of

safety.

3. Determine the factor of safety based

on joint separation.

4. Determine the fatigue factor of

safety using the Goodman criterion
