Torsional shear stress acts whenever a shaft is subjected to torsion. simple shear stress is same on all the layers of a component acted by two opposing forces in a single plane. while torsional shear stress varies from inside to periphery being maximum at periphery as it is proportional to the distance from the center.

Axial Load on Close-coiled Helical Spring
Introduction:
A close-coiled helical spring is a mechanical device that is used to store and release energy. When an axial load is applied to the spring, it undergoes deformation due to the stress induced in it.
Types of Stress:
The stress induced in a close-coiled helical spring is of two types:
Effect of Axial Load:
When an axial load is applied to a close-coiled helical spring, it undergoes deformation due to the stress induced in it. The stress induced in the spring is of two types:
Conclusion:
Hence, under axial load, each section of a close-coiled helical spring is subject to torsional and direct shear stress.
Introduction:
A close-coiled helical spring is a mechanical device that is used to store and release energy. When an axial load is applied to the spring, it undergoes deformation due to the stress induced in it.
Types of Stress:
The stress induced in a close-coiled helical spring is of two types:
- Torsional stress: Torsional stress is the stress induced due to the torque applied to the spring. It is a shear stress that acts perpendicular to the cross-section of the spring.
- Direct shear stress: Direct shear stress is the stress induced due to the axial load applied to the spring. It is a shear stress that acts parallel to the cross-section of the spring.
Effect of Axial Load:
When an axial load is applied to a close-coiled helical spring, it undergoes deformation due to the stress induced in it. The stress induced in the spring is of two types:
- Torsional stress: When an axial load is applied to the spring, it causes the spring to twist. This twisting action induces torsional stress in the spring.
- Direct shear stress: When an axial load is applied to the spring, it causes the coils of the spring to slide over each other. This sliding action induces direct shear stress in the spring.
Conclusion:
Hence, under axial load, each section of a close-coiled helical spring is subject to torsional and direct shear stress.
