Machine Design The connecting rod bolts are tightened up with initial tension greater than the external load so that 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 Bolts are weakest elements Bolts will not loosen during service ANSWER DOWNLOAD EXAMIANS APP
Machine Design A closely coiled helical spring is acted upon by an axial force. The maximum shear stress developed in the spring is τ. The half of the length of the spring if cut off and the remaining spring is acted upon by the same axial force. The maximum shear stress in the spring in new condition will be τ 4 τ τ/2 2 τ τ 4 τ τ/2 2 τ ANSWER DOWNLOAD EXAMIANS APP
