Reference Answer

### (a) Rudder Hinges or Pintles
The hinges of a semi-balanced rudder are comprised of pintles and gudgeons, which connect the rudder to the stern frame and allow it to pivot.
* **Pintle:** A robust, large-diameter pin, typically made of forged steel. The pintle is fixed to the stern frame, projecting outwards.
* **Gudgeon:** A corresponding socket or boss forged as part of the rudder structure. The gudgeon fits over the pintle.
