🔍 Key Concepts

• Electro-hydraulic steering gear basic layout (wheel, telemotor, pump, ram, feedback linkage) • What follow‑up control or feedback means in control systems • How the steering gear knows when the ordered rudder angle has been reached

💭 Think About

• Think about how the steering gear stops the rudder from turning past the angle ordered at the wheel—what part does that job? • Which choice describes a control function (stopping or correcting movement) rather than a safety function (pressure relief) or an automatic centering feature? • In an electro‑hydraulic system, what has to happen to the pump output or valve position when the rudder reaches the angle you ordered?

✅ Before You Answer

• Identify which option describes a feedback / follow‑up action (comparing actual rudder angle to ordered angle). • Eliminate any choices that sound like pressure protection or automatic return to mid‑ships, which are different functions. • Ask yourself: which option explains how the system automatically stops further rudder movement once the correct angle is reached?
