Pulley is?

Pulley is?

• A. Grooved wheel that halyard is pulled through
• B. A type of hook
• C. A measurement tool
• D. A protective cap

Answer: (A)

A pulley is a grooved wheel that guides a rope or halyard, allowing you to change the direction of your pull and reduce the effort needed to lift or lower a load. In firefighting, the rope runs through the wheel to redirect force and often to gain mechanical advantage, making it easier to haul equipment or victims. This definition fits best because it specifically describes the wheel-with-a-groove and the way the rope or halyard moves through it. It isn’t a hook, a measurement tool, or a protective cap, which are different components or devices.
