Machine Design A shaft is subjected to a maximum bending stress of 80 N/mm² and maximum shearing stress equal to 30 N/mm² at a particular section. If the yield point in tension of the material is 280 N/mm² and the maximum shear stress theory of failure is used, then the factor of safety obtained will be 3.0 2.5 3.5 2.8 3.0 2.5 3.5 2.8 ANSWER DOWNLOAD EXAMIANS APP
Machine Design The connecting rod bolts are tightened up with initial tension greater than the external load so that Bolts are weakest elements Bolts will not loosen during service Joint may not open up The resultant load on the bolt would not be affected by the external cyclic load Bolts are weakest elements Bolts will not loosen during service Joint may not open up The resultant load on the bolt would not be affected by the external cyclic load ANSWER DOWNLOAD EXAMIANS APP
