Machine Design The ratio of belt tensions (p1/p2) considering centrifugal force in flat belt is given by Where m = mass of belt per meter (kg/m) v = belt velocity (m/s) f = coefficient of friction a = angle of wrap (radians) (P1 - mv²)/ (P2 - mv²) = eᶠα (P1 - mv²)/ (P2 - mv²) = e–ᶠα P1 / P2 = e–ᶠα P1 / P2 = eᶠα (P1 - mv²)/ (P2 - mv²) = eᶠα (P1 - mv²)/ (P2 - mv²) = e–ᶠα P1 / P2 = e–ᶠα P1 / P2 = eᶠα 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 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
