Machine Design The initial tension (in newtons) in a bolt used for making a fluid tight joint like steam engine cover joints, is calculated by the relation (where d = Nominal diameter of bolt in mm) 2080 d 1680 d 2840 d 1420 d 2080 d 1680 d 2840 d 1420 d ANSWER DOWNLOAD EXAMIANS APP
Machine Design The resultant axial load on a bolt depends upon Relative elastic yielding of the bolt and the connected members Initial tension due to tightening of the bolt All of these External load applied Relative elastic yielding of the bolt and the connected members Initial tension due to tightening of the bolt All of these External load applied ANSWER DOWNLOAD EXAMIANS APP
Machine Design When the bolt is very yielding as compared to the connected members, then the resultant load on the bolt will be equal to the Sum of the initial tension and external load applied External load applied Initial tension or external load, whichever is greater Initial tension Sum of the initial tension and external load applied External load applied Initial tension or external load, whichever is greater Initial tension ANSWER DOWNLOAD EXAMIANS APP
