70% to passWhich of the listed types of bearings is an example of a half bearing?
APiston pin bushing
BSpring bearing
CThrust bearing
DAll of the above.
AI Explanation
The correct answer is B) Spring bearing. A spring bearing is an example of a half bearing, which is a type of bearing that only supports the load over a portion of the bearing surface. In contrast, a full bearing supports the load over the entire bearing surface. The other options are not examples of half bearings. Piston pin bushings, thrust bearings, and other types of bearings may be full or partial bearings, but they are not specifically considered half bearings in the context of the US Coast Guard Captain's License Examinations.
