Question 10General Subjects - 1st Asst/Chief

The correct answer is B) Ball. A ball bearing is the best choice to carry the load on two small points diametrically opposite to each other. Ball bearings are designed to support radial loads, which means they can effectively transfer the load between the inner and outer races at the two opposing contact points. The spherical shape of the balls allows them to roll smoothly between the races, evenly distributing the load. The other options, such as tapered roller bearings (A), needle bearings (C), and standard roller bearings (D), are not as well-suited for this type of load configuration, as they are typically designed to handle different types of loads and load distributions.
