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)

A. σ [1 + (b/2a)]

B. σ [1 + (2a/b)]

C. σ [1 + (b/3a)]

D. σ [1 + (3a/b)]
