1. What is the core principle?Application of mechanical advantage via ropes and pulleys to augment steering force
2. What is the strategic significance?Provided steering redundancy critical for naval combat survivability and maneuverability
3. Why did sailors use relieving tackle instead of just a wheel?Before ships had big wheels with gears, steering was done with a whipstaff or tiller that needed a lot of strength. Relieving tackle gave extra leverage so one person could control the ship.
4. How does relieving tackle help in a storm?It reduces the effort a helmsman has to use, letting them keep the ship on course even when waves push hard on the rudder. It keeps the ship from spinning out of control.

Hydrodynamic Forces: The forces exerted by moving water on an object, like a ship's rudder.
Mechanical Advantage: Using a tool or system to reduce the force needed to perform a task.
Redundancy (Engineering): The duplication of critical components or functions to increase reliability.
