Which bearing will carry the load on two small points diametrically opposite to each other?
Official USCG Answer & Rule Citation
Correct Answer: Option D — Ball
Ball bearings utilize spherical rolling elements that contact the inner and outer races at essentially two points. This geometry allows for high-speed operation and moderate load capacity, though it is susceptible to point-loading stress compared to the line contact provided by roller or needle bearing designs.
