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.P F + P F P F.P F + P F P ANSWER DOWNLOAD EXAMIANS APP
Machine Design A plate with an elliptical hole in the centre, with semi-major axis (a) perpendicular to the direction of loading and semi-minor axis (b) along the direction of loading, is subjected to a pull P. The maximum stress induced at the edge of the hole is equal to (where σ = Stress for a plate with no hole i.e. nominal stress) σ [1 + (2a/b)] σ [1 + (b/3a)] σ [1 + (3a/b)] σ [1 + (b/2a)] σ [1 + (2a/b)] σ [1 + (b/3a)] σ [1 + (3a/b)] σ [1 + (b/2a)] ANSWER DOWNLOAD EXAMIANS APP
