Which of the listed types of bearings is an example of a half bearing?

AI Explanation
The correct answer is C) Spring bearing. A spring bearing is an example of a half bearing, which is a type of bearing that supports a load over only a portion of the surface area. Spring bearings are typically used in applications where the load on the bearing is intermittent or variable, as they can accommodate these changes more effectively than a full bearing. The other options are not examples of half bearings. Thrust bearings support axial loads, piston pin bushings support the reciprocating motion of a piston, and none of these are considered half bearings.
