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 2W/3 W/2 W/9 8W/9 2W/3 W/2 W/9 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 2.5 3.5 2.8 3 2.5 3.5 2.8 3 ANSWER DOWNLOAD EXAMIANS APP
