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 + (3a/b)] σ [1 + (b/2a)] σ [1 + (2a/b)] σ [1 + (b/3a)] σ [1 + (3a/b)] σ [1 + (b/2a)] σ [1 + (2a/b)] σ [1 + (b/3a)] ANSWER DOWNLOAD EXAMIANS APP
