The formula to calculate the Torsional Shear Stress (σs) is:
\[ \sigma_s = \frac{3 \cdot M_{tt}}{h_t \cdot L^2} \]
Torsional Shear Stress is the shear stress produced against torsional load or twisting load. Torsional moment in welded shaft is the torque applied to generate a torsion (twist) within the shaft. Throat thickness of weld is the shortest distance from the root to the face of the weld. The Length of Weld is the linear distance of the welding segment joined by the welded joint.
Let's assume the following values:
Using the formula:
\[ \sigma_s = \frac{3 \cdot 1300}{0.015 \cdot 0.195^2} \approx 6837606.83760684 \]
The Torsional Shear Stress is approximately 6837606.83760684 Pascal.
