The force exerted by a propeller which tends to throw the stern right or left is called _______________.
AI Explanation
The correct answer is C) sidewise force.
The sidewise force exerted by a propeller is the force that tends to throw the stern of the vessel to the right or left. This is caused by the rotational effect of the propeller, which creates an asymmetric flow of water around the hull, resulting in a sideways force on the stern. This phenomenon is well-known in the operation of vessels and is an important factor to consider in maneuvering and handling a vessel, especially in close-quarters situations.
The other options are incorrect because slip refers to the difference between the speed of the propeller and the speed of the vessel, rotational force is a more general term, and thrust is the forward force generated by the propeller.
