70% to passTo properly remove the burner tip nut from the burner barrel, the barrel should be _______________.
Aclamped in a machinist's vice on the work bench
Bfixed in the burner stowage rack
Cheld by the fixture on the burner cleaning bench
Dremoved from the gooseneck before removing the tip nut
AI Explanation
The correct answer is C) held by the fixture on the burner cleaning bench. The burner tip nut should be removed while the burner barrel is securely held in a fixture on the burner cleaning bench. This allows the barrel to be stabilized and properly oriented to access the tip nut without risk of damage. Clamping the barrel in a vice (A) or leaving it in the stowage rack (B) would not provide the necessary stability and access. Removing the barrel from the gooseneck (D) is unnecessary for just removing the tip nut.
