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

Machine Design A shaft is subjected to a maximum bending stress of 80 N/mm² and maximum shearing stress equal to 30 N/mm² at a particular section. If the yield point in tension of the material is 280 N/mm² and the maximum shear stress theory of failure is used, then the factor of safety obtained will be 3 3.5 2.8 2.5 3 3.5 2.8 2.5 ANSWER DOWNLOAD EXAMIANS APP
