A threaded rod and nut arrangement are guided with two washers, upper and lower washers tightened into a base plate. Considering that the base plate carries a load of 120 kNincluding its self-weight which is distributed equally: a.Determine the stress on the lower washers before the buts are tightened. b.Determine the stress int the upper washer when the nuts are tightened so as to produce a tension of 5kN on the bolt. c.Determine the stress int the lower washer when the nuts are tightened so as to produce a tension of 5kN on the bolt.
