Why Crane is a movable pulley?
Many of the weight lifting machines have movable pulleys inside them as well. This allows the person working out to use less effort to lift a given amount of weight, which helps them to work out safely and avoid injury. Cranes (the big machines that you might see at a construction sight) are movable pulleys as well.
What type of pulley is used in flagpole?
A flag pole usually uses a fixed pulley to move the flag up or down. Fixed pulleys may be used in warehouses to lift loads off of trucks or trains. A fixed pulley works by changing the direction of the force and allowing you to raise things above your head (such as a flag up a flagpole).
How many pulleys are used in a flagpole?
A single revolving truck has one pulley and a double revolving truck has two pulleys. External Halyard: This refers to the rope system used to raise and lower the flag being on the outside of the flagpole. Finial/Ornament: The finial and/or ornament references the standard gold ball that sits atop most flagpoles.
