With respect to shaft bearing load absorption capability in terms of direction, what is meant by a radial load?

Correct Answer: Option A — A radial load is a load applied perpendicular to the axis of the shaft.

Radial loads are defined as forces acting perpendicular to the longitudinal axis of a rotating shaft. These loads are typically generated by the weight of the shaft, belt tension, or gear forces, and are supported by radial bearings designed to resist these lateral stresses during normal machinery operation.
