Machine Design A closely coiled helical spring is acted upon by an axial force. The maximum shear stress developed in the spring is τ. The half of the length of the spring if cut off and the remaining spring is acted upon by the same axial force. The maximum shear stress in the spring in new condition will be τ 4 τ 2 τ τ/2 τ 4 τ 2 τ τ/2 ANSWER DOWNLOAD EXAMIANS APP

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 + (b/3a)] 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)] ANSWER DOWNLOAD EXAMIANS APP
