Question 1 of 27070

Q

The horizontal flat surfaces where the upper stock joins the rudder are the __________.

🔍 Key Concepts

• Rudder construction terminology used in ship design • How the rudder stock connects to the main rudder blade • Functions of parts like palm, shoe, key, flange in transmitting force and supporting the rudder

💭 Think About

• Think about which part of the rudder actually bears against the stock to transmit turning force from the steering gear to the rudder blade. • Which of these terms refers to a broad, flat connection surface, rather than a small locking piece or a support at the bottom? • Consider where lifting or supporting forces would act versus where torque (twisting force) from the stock is carried into the rudder.

✅ Before You Answer

• Match each term to its main function: locking, supporting, lifting, or transmitting torque. • Visualize the upper connection between stock and blade, not the bottom support or securing pins. • Ask yourself which option best describes flat bearing surfaces rather than pins, bolts, or brackets.
