When measuring sideways deformation of the gooseneck bolster web, what area should be used?

When measuring sideways deformation of the gooseneck bolster web, the appropriate area to evaluate is the undamaged area. This choice is essential because assessing deformation in a region that has not been compromised provides a more accurate baseline for understanding the structural integrity of the bolster web. By focusing on the undamaged area, you can better distinguish between normal variations and significant deformations that may indicate potential issues with the trailer’s performance or safety.

In contrast, examining a damaged area would not yield reliable data, as existing damage could have already altered the geometry and load-bearing capacity of the bolster web. The top face of the bottom side rail may not be directly relevant to measuring the deformation within the gooseneck bolster web, as it pertains to a different structural component. Meanwhile, the flange area, while part of the assembly, does not specifically address the deformation being measured in the bolster web context.

Thus, evaluating the undamaged area is critical for ensuring accurate measurements and maintaining the effectiveness of the inspection process.
