70% to passOn a main propulsion turbine bearing, the readings obtained with a bridge gage represent the _______________.
Ablade axial clearance
BBabbitt thickness
Coil clearance and bearing wear
Ddiaphragm tip clearance
AI Explanation
The correct answer is C) oil clearance and bearing wear. The readings obtained with a bridge gage on a main propulsion turbine bearing represent the oil clearance and bearing wear. This is because a bridge gage is used to measure the gap or clearance between the bearing journal and the bearing housing, which is directly related to the oil clearance and the amount of wear on the bearing. The other options (A, B, and D) do not directly correspond to the measurements taken with a bridge gage on a main propulsion turbine bearing.
