🔍 Key Concepts

• Design and safety features of electric cargo winches • What happens to electromagnets and motor torque when electrical power is lost • How mechanical devices like pawls, brakes, and gears behave without power

💭 Think About

• Think about which system parts rely on electric current to work and which are purely mechanical. • If all electric power disappears instantly, which option describes a behavior that could still happen without any electricity at all? • Consider what a well-designed cargo winch must do in a blackout to prevent a dangerous runaway load.

✅ Before You Answer

• Identify which options describe devices that need electric power to remain engaged. • Decide which options describe an action that requires active human input at the exact moment of power loss. • Ask which mechanism would be considered a fail-safe design for holding a suspended load during a total power failure.
