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 W/9 2W/3 W/2 8W/9 W/9 2W/3 W/2 8W/9 ANSWER DOWNLOAD EXAMIANS APP
Machine Design When the connected members are very yielding (soft gasket) as compared to the bolt, then the resultant load on the bolt will be equal to the Initial tension Initial tension or external load, whichever is greater Sum of the initial tension and external load applied External load applied Initial tension Initial tension or external load, whichever is greater Sum of the initial tension and external load applied External load applied ANSWER DOWNLOAD EXAMIANS APP
