A flat leaf spring has fluctuating stress of max = 420 MPa and min = 140 MPa

Question:

A flat leaf spring has fluctuating stress of σmax = 420 MPa and σmin = 140 MPa applied for 5 (104) cycles. If the load changes to σmax = 350 MPa and σmin = .200 MPa, how many cycles should the spring survive? The material is AISI 1040 CD and has a fully corrected endurance strength of Se = 200 MPa. Assume that f = 0.9.
(a) Use Miner’s method.
