The formula to calculate the Stress Amplitude (Fatigue) is:
\[ \sigma_a = \frac{\sigma_r}{2} \]
Stress amplitude is one half of the range of stress of a stress cycle in fatigue. The range of stress is the difference between the maximum and minimum stress in a stress cycle during fatigue.
Let's assume the following value:
Using the formula:
\[ \sigma_a = \frac{10,000,000}{2} \approx 5,000,000 \, \text{Pascals} \]
The Stress Amplitude is approximately 5,000,000 Pascals.
