Machine Design If P1 and P2 are the tight and slack side tensions in the belt, then the initial tension Pi (according to Barth) will be equal to (Where, Pc is centrifugal tension) P1 + P2 [(√P1 + √P2)/2]² [⅟₂ × (P1 + P2)] + Pc ⅟₂× (P1 + P2) P1 + P2 [(√P1 + √P2)/2]² [⅟₂ × (P1 + P2)] + Pc ⅟₂× (P1 + P2) ANSWER DOWNLOAD EXAMIANS APP
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 F F + P P F.P F F + P P F.P ANSWER DOWNLOAD EXAMIANS APP
