Question 86General Subjects - Assistant Engineer

The correct answer is A) An axial load is a load applied parallel to the axis of the shaft. This is correct because an axial load refers to a force that is applied along the longitudinal or central axis of the shaft. This type of load is directed parallel to the shaft's axis and causes the shaft to either stretch or compress along its length. The other answer choices are incorrect because: B) a tangential load is applied perpendicular to the shaft's axis, C) a combined axial and radial load is applied in multiple directions, and D) a radial load is applied perpendicular to the shaft's axis.
