High cycle fatigue data for an alloy at various alternating stresses, š_{a} (see figure) is given below.

A specimen of this alloy is subjected to multiple stress cycles sequentially in the following order: (i) first 5000 cycles at Ļa = 400 MPa followed by (ii) 25000 cycles at Ļa = 300 MPa and finally (iii) at Ļa = 500 MPa. Assuming that Minerās law is obeyed, the number of cycles to failure at the final applied stress of

500 MPa is .
