Consider a bolted joint which used an m14 x 2 x 50 bolt used to fasten two steel plates together. all materials in the joint were steel with e = 207 gpa. the bolt will be made from metric iso class 5.8 steel. assume that the following stiffness values apply for this bolted joint: k = 9 x 10' n/mm (effective bolt stiffness for this geometry) km = 2.7 x 100 n/mm (combined stiffness for both plates for this bolt size) - 1. the portion of an external load (c) that would be carried by the bolt is: (assume that the joint has not separated.) 2. for a bolt made from metric class 5.8 steel, the minimum proof strength for this material is: (from table: kn is needed to prevent separation assuming a 3. for an external force of 10 kn, a preload of factor of safety of 1.0. 4. for the bolt in part (c), assuming you designed the joint to separate at 10 kn and an external load of 12 kn is applied, the joint will / will not (circle one) separate. the factor of safety against static proof failure is: and the bolt will / will not (circle one) yield. 5. for the bolt in part (c), assuming you designed the joint to separate at 10kn and an external load of 8 kn is applied, the joint will / will not (circle one) separate. the factor of safety against static proof failure is: and the bolt will / will not (circle one) yield. 6. for an external load of 15 kn and a factor of safety against joint separation, nsep, of 1.5, the minimum bolt preload should be: n. 7. for an external load of 15 kn and a factor of safety against yielding of the bolt, nproof, of 2.0, the maximum preload should be: _n, assuming no joint separation.
