🔍 Key Concepts

• Transverse thrust (paddle‑wheel effect) of a single screw in reverse • How pressure differences are created around a rotating propeller • The difference between forces caused by the propeller itself vs. forces caused by the rudder

💭 Think About

• Ask yourself: Is the side force mainly created by what happens directly on the propeller blades, or by the water flow after it leaves the propeller? • Which option best describes a force created by unequal pressure on different sides of the propeller disk, rather than by flow hitting another surface? • Does the rudder need to be involved at all for this sidewise force to exist?

✅ Before You Answer

• Identify which choices clearly involve the rudder or wake rather than the propeller’s own action. • Look for the option that directly describes uneven pressure on one side of the propeller vs. the other. • Verify that the cause you pick would still exist even if the rudder were hard over, amidships, or even missing. The correct cause should not depend on rudder position.

Question 1 of 20

Sidewise force of the propeller tends to throw a vessel's stern to the right or left, depending on rotation. Which causes this force?

Greater pressure on the right or left side of the propeller, depending on rotation

Lower pressure on the right or left side of the propeller, depending on rotation

The back current from the rudder

The torque from the velocity and angle at which the surrounding water impinges upon the propeller blades
