70% to passThe splits located in the halves of main reduction gear bearings are aligned at an angle to the horizontal in order to resist _______________.
Awiping
Bsteam loss
Coil loss
Daxial stress
AI Explanation
The correct answer is A) wiping. The splits located in the halves of main reduction gear bearings are aligned at an angle to the horizontal in order to resist wiping. This angled split design helps to prevent the bearing surfaces from sliding or "wiping" against each other, which can occur due to the high loads and rotational forces present in the reduction gear system. The other answer choices are incorrect because they do not address the primary purpose of the angled split design. Steam loss, oil loss, and axial stress are not the main reasons for this specific bearing configuration.
