Question 85General Subjects - QMED

The correct answer is A) Ball. A ball bearing is best suited to carry the load on two small points diametrically opposite to each other. Ball bearings are designed to support radial loads, which are forces applied perpendicular to the bearing's axis of rotation. The spherical shape of the balls allows them to efficiently distribute the load between the inner and outer races of the bearing, making it an ideal choice for this type of application. The other options, such as roller bearings, tapered roller bearings, and needle bearings, are not as well-suited for this specific load configuration, as they are typically designed to handle different types of loads or have different geometries that may not be as effective in this scenario.
