Machine Design Two helical springs of the same material and of equal circular cross-section, length and number of turns, but having radii 80 mm and 40 mm, kept concentrically (smaller radius spring within the larger radius spring), are compressed between two parallel planes with a load W. The inner spring will carry a load equal to 8W/9 W/9 2W/3 W/2 8W/9 W/9 2W/3 W/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 + (3a/b)] 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)] ANSWER DOWNLOAD EXAMIANS APP
