Question 81General Subjects - Assistant Engineer

The correct answer is D) Ball. A ball bearing is the best option to carry the load on two small points diametrically opposite to each other. Ball bearings are designed to support radial and axial loads efficiently by rolling between the inner and outer races. The spherical shape of the balls allows them to distribute the load evenly across the contact points, making ball bearings well-suited for applications with concentrated loads. The other options, such as roller bearings, tapered roller bearings, and needle bearings, are not as well-suited for this specific application because they are designed to handle different types of loads and forces more effectively.
