0Following are the assumptions made for the derivation of torsion equation:
- The material is homogeneous (elastic property throughout)
- The material should follow Hook’s law
- The material should have shear stress proportional to shear strain
- The cross-sectional area should be plane
- The circular section should be circular
- Every diameter of the material should rotate through the same angle
- The stress of the material should not exceed the elastic limit
