Bearing strength of single riveted lap joint is equal to d x t x fb.

Explanation:

Bearing strength is the maximum load that can be applied to a joint before the plates in the joint start to deform. In the case of a single riveted lap joint, the load is carried by the rivets. The bearing strength of the joint depends on the diameter of the rivet, the thickness of the plates, and the allowable bearing stress of the material.

The formula for the bearing strength of a single riveted lap joint is given by:

Bearing strength = d x t x fb

Where, d = diameter of the rivet
t = thickness of the plate
fb = allowable bearing stress of the material

The bearing strength is directly proportional to the diameter of the rivet and the thickness of the plate. Therefore, using a larger diameter rivet or increasing the thickness of the plate can increase the bearing strength of the joint.

However, the bearing strength is limited by the allowable bearing stress of the material. If the bearing stress exceeds the allowable value, the material will start to deform and the joint will fail. Therefore, it is important to choose the appropriate material with suitable bearing stress to ensure the joint can withstand the required load.

In conclusion, the bearing strength of a single riveted lap joint is equal to d x t x fb, which depends on the diameter of the rivet, the thickness of the plate, and the allowable bearing stress of the material.
