Structural parts are the skeleton of the machine — brackets, supports, arms, and frames that hold everything working parts in the right spot. When they get bent from an impact or worn at a pivot, the parts they're supporting stop being where they need to be. And that shows up as a "why isn't this working right" problem, not a "why is this bracket bent" problem.
