Acritical component for a mechanical system will be subjected to a 0.01 hz cyclical stress during operation (0.01 cycles per second). the stress will fluctuate between a tensile load of 150 mpa and a compressive load of -250 mpa. the design calls for a survival rate of 90% (i. e. 10% failure rate acceptable). approximately how long, in days, can the component be used before it must be replaced during maintenance ? answer format: x (no decimal) answer unit: day the fatigue lifetime curves (for various confidence intervals) for the material are given below. if you don't immediately recall, you should be able to conceptually discern whether the "p = x" label indicates a probability of failure or survival. note on this figure, s stands for stress amplitude.
