🔍 Key Concepts

• Electro-hydraulic steering system basic layout: wheel, control unit, telemotor, power unit, and ram • How a steering system keeps the rudder angle matched to the ordered wheel angle • Difference between manual non-follow-up control and automatic follow-up control

💭 Think About

• Which component or method in a steering system is specifically designed to compare the commanded wheel position with the actual rudder position and continually adjust until they match? • Look at each choice and ask: is this mainly a type of valve, a mechanical linkage, a local emergency device, or an automatic control function? • In modern electro-hydraulic systems, what do we call the system that stops the rudder automatically when it reaches the angle ordered at the wheel?

✅ Before You Answer

• Identify which option refers to an automatic control function, not just a physical part like a valve or linkage • Ask yourself which item is normally associated with rudder angle feedback and keeping wheel order and rudder position synchronized • Eliminate any option you know is used mainly for emergency/auxiliary steering or for older mechanical linkage arrangements rather than automatic electro-hydraulic control
