Machine Design Two rigid plates are clamped by means of bolt and nut with an initial force F. After tightening, a separating force P (P < F) is applied to the lower plate, which in turn acts on the nut. The tension in the both after this is P F + P F.P F P F + P F.P F ANSWER DOWNLOAD EXAMIANS APP
Machine Design According to I.B.R., shearing resistance required to shear off the rivet per pitch length (in double shear) is (where n = Number of rivets per pitch length) 2 × (π/4) d² × τ × n 3 × (π/4) d² × τ × n 1.875 × (π/4) d² × τ × n (π/4) d² × τ × n 2 × (π/4) d² × τ × n 3 × (π/4) d² × τ × n 1.875 × (π/4) d² × τ × n (π/4) d² × τ × n ANSWER DOWNLOAD EXAMIANS APP
Machine Design The connecting rod bolts are tightened up with initial tension greater than the external load so that Joint may not open up Bolts are weakest elements The resultant load on the bolt would not be affected by the external cyclic load Bolts will not loosen during service Joint may not open up Bolts are weakest elements The resultant load on the bolt would not be affected by the external cyclic load Bolts will not loosen during service ANSWER DOWNLOAD EXAMIANS APP
