To calculate the torsional shear stress in a structure, the following formula can be used:
Torsional Shear Stress = (Torsional Moment x Radius)/Polar Moment of Inertia
Where:
- Torsional Moment: It is the twisting moment or torque that is applied to the structure.
- Radius: It is the distance between the center of the structure and the point of interest where the torsional shear stress is to be calculated.
- Polar Moment of Inertia: It is the resistance of a cross-sectional area of a structural element to torsion.
Once the values of the torsional moment, radius, and polar moment of inertia are known, they can be inserted into the above formula to calculate the torsional shear stress in the structure.
