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/3a)] σ [1 + (2a/b)] σ [1 + (b/2a)] σ [1 + (3a/b)] σ [1 + (b/3a)] σ [1 + (2a/b)] σ [1 + (b/2a)] ANSWER DOWNLOAD EXAMIANS APP
Machine Design The cracks in helical springs used in railway carriages usually start on the inner side of the coil because of the fact that It has a lower curvature than the outer side It is subjected to a higher stress than the outer side It is subjected to a higher cyclic loading than the outer side It is more stretched than the outer side during the manufacturing process It has a lower curvature than the outer side It is subjected to a higher stress than the outer side It is subjected to a higher cyclic loading than the outer side It is more stretched than the outer side during the manufacturing process ANSWER DOWNLOAD EXAMIANS APP
