Structural and Stress Analysis [EXP-43438]

A structural member is to be subjected to a series of cyclic loads which produce different levels of alternating stress as shown below. Determine whether or not a fatigue failure is probable.

Table P.8.4
Loading	Number of Cycles	Number of Cycles to Failure
1	$10^{4}$	$5 \times 10^{4}$
2	$10^{5}$	$10^{6}$
3	$10^{6}$	$24 \times 10^{7}$
4	$10^{7}$	$12 \times 10^{7}$
