Final answer:
The correct grip length of a bolt used in an aircraft structure is determined by factors such as the material being fastened, the thickness of the materials, and the type of joint.
Step-by-step explanation:
In aircraft structures, the correct grip length of a bolt is determined by several factors:
-
- The material being fastened together
-
- The thickness of the materials being fastened
-
- The type of joint being formed
The grip length is the portion of the bolt that extends through the materials being joined, and it should be long enough to provide enough thread engagement without protruding too far. This ensures proper clamping force and prevents damage to the materials. For example, in a lap joint, the grip length will depend on the combined thickness of the two overlapping parts of the joint.
