Machine Design The connecting rod bolts are tightened up with initial tension greater than the external load so that Bolts will not loosen during service The resultant load on the bolt would not be affected by the external cyclic load Bolts are weakest elements Joint may not open up Bolts will not loosen during service The resultant load on the bolt would not be affected by the external cyclic load Bolts are weakest elements Joint may not open up ANSWER DOWNLOAD EXAMIANS APP
Machine Design When the connected members are very yielding (soft gasket) as compared to the bolt, then the resultant load on the bolt will be equal to the Initial tension or external load, whichever is greater External load applied Initial tension Sum of the initial tension and external load applied Initial tension or external load, whichever is greater External load applied Initial tension Sum of the initial tension and external load applied ANSWER DOWNLOAD EXAMIANS APP
