Explanation:

In a riveted joint, failure can occur due to various reasons such as shear failure of the rivet, bearing failure of the rivet, or tearing failure of the plate. However, the correct answer to this question is option D, which states that failure will occur when the load reaches the minimum value required for shearing, bearing, or tearing failure.

Riveted joints are commonly used to join two or more plates together in structural applications. The joint consists of a rivet that is inserted through holes in the plates and then deformed to create a permanent connection. The rivet is usually made of a ductile material such as steel, while the plates can be made of various materials such as steel, aluminum, or composite materials.

Shear Failure of Rivet:
Shear failure of the rivet occurs when the applied load causes the rivet to shear along its cross-section. This type of failure is influenced by the shear strength of the rivet material. If the applied load exceeds the shear strength of the rivet, it will fail in shear.

Bearing Failure of Rivet:
Bearing failure of the rivet occurs when the applied load causes the rivet to deform and fail due to excessive pressure between the rivet and the hole in the plate. This type of failure is influenced by the bearing strength of the rivet material and the plate material. If the applied load exceeds the bearing strength, it will cause the rivet to fail.

Tearing Failure of Plate:
Tearing failure of the plate occurs when the applied load causes the plate to tear or fracture along the edges of the hole. This type of failure is influenced by the tensile strength of the plate material. If the applied load exceeds the tensile strength of the plate, it will cause tearing failure.

Minimum Load Value for Failure:
The minimum load value required for failure depends on the weakest component in the joint, whether it is the rivet or the plate. The load should be limited to the minimum value required to prevent any of the failure modes mentioned above. This ensures the joint's structural integrity and prevents catastrophic failure.

In conclusion, while shear failure of the rivet, bearing failure of the rivet, and tearing failure of the plate are all potential failure modes in a riveted joint, failure will occur when the load reaches the minimum value required for shearing, bearing, or tearing failure. It is important to consider the strength of both the rivet and the plate to ensure the joint can withstand the applied loads without failure.
