For a bolted assembly with six bolts, the stiffness of each bolt is kb = 2 mlbf/in and the stiffness of the members is km = 14 mlbf/in per bolt. an external load of 80 kips is applied to the entire joint. assume the load is equally distributed to all the bolts. it has been determined to use 1/2 in-13 unc grade 8 bolts with rolled threads. it is desired to ﬁnd the range of torque that a mechanic could apply to initially preload the bolts without expecting failure once the joint is loaded. assume a torque coefﬁcient of k = 0.2.

a. determine the yielding factor of safety.
b. determine the overload factor of safety
