Explanation:

Maximum Strain Energy Theory

- This theory postulates that failure will occur when the strain energy per unit volume due to the applied stresses in a part equals the strain energy per unit volume at the yield point in uniaxial testing.
- In simpler terms, failure happens when the energy stored in a material due to applied stresses reaches a critical point.

Understanding Option A

- In the context of the given options, option A aligns with the Maximum Strain Energy Theory.
- When the applied stresses in a part reach a level where the strain energy per unit volume equals the strain energy per unit volume at the yield point in uniaxial testing, failure is likely to occur.
- This criterion is based on the comparison of the energy levels in the material, indicating that the material has reached its limit and is likely to fail.

Conclusion

- Option A is the correct choice because it accurately describes the conditions under which failure is predicted to happen based on the Maximum Strain Energy Theory.
- By understanding this theory and its implications, engineers and designers can make informed decisions to prevent failure in structural components.
