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

Correct Answer: Option A — An axial load is a load applied parallel to the axis of the shaft.

Axial loads, also known as thrust loads, are forces applied parallel to the axis of a rotating shaft. These are common in marine propulsion systems, such as the propeller thrust acting on the main shaft, requiring specialized thrust bearings to absorb the force and prevent longitudinal shaft movement.
