The stress in the bar when the load is applied suddenly is __________ as compared to the stress induced due to gradually applied loads.

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
