The tensile area is the cross-sectional area of the bolt that is subjected to tensile stress. It is crucial for determining the strength of the bolt under tension.
The formula to calculate the tensile area of a partial thread is:
\[ A_t = \frac{\pi}{4} \left(D - 0.938194 \cdot p\right)^2 \]
Consider the following details:
Using the formula:
\[ A_t = \frac{\pi}{4} \left(10 - 0.938194 \cdot 1.5\right)^2 = 57.99 \, \text{mm}^2 \]
