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 + (b/2a)] σ [1 + (3a/b)] σ [1 + (2a/b)] σ [1 + (b/3a)] σ [1 + (b/2a)] σ [1 + (3a/b)] ANSWER DOWNLOAD EXAMIANS APP
Machine Design The elasticity is the property of a material which enables it to Draw into wires by the application of a tensile force Retain deformation produced under load permanently Resists fracture due to high impact loads Regains its original shape after deformation when the external forces are removed Draw into wires by the application of a tensile force Retain deformation produced under load permanently Resists fracture due to high impact loads Regains its original shape after deformation when the external forces are removed ANSWER DOWNLOAD EXAMIANS APP
