Problem 2 The following lap joint uses one row of 5mm bolts. The top plate is 10mm thick, the bottom plate is 5mm thick. The bolt is completely threaded, there is no shank region. Plate holes for bolts are untapped. Assume the von mises theory of failure. Assume the plates are much larger than the bolts. Assume all parts are made from SAAE 1020 cold rolled steel. 500mm 100mm 10lbs | 100mm a). What is the maximum number of bolts I can place in the joint if minimum margins and pitch are used? b). The thread call out for your bolts are M5 x .8. What is the pitch and the number of threads per inch? c) What are dp and dr for the bolt? d). Assume the nut available for this bolt are 5m in length. What is the minimum length required for the bolt? e). Please calculate the safety factor of the joint.
Problem 3 The same joint as in problem 2, but now the plates are loaded with a 10lbs force trying to split them apart. Also assume three bolts are in the row. Available nuts are 5mm in length. Please calculate safety factor for joint? What is the load factor. Assume static loading and that the bolt will not be reused. You can assume Sp=.85Sy and von mises theory of failure.
Problem 4 Repeat problem 3 if the external load cycles between 0 and 10lbs. What is the torque required to achieve the preload? Assume a friction factor of 0.15.
