a pulley.
Actually, it's "block and tackle"; as in, "The block and tackle was described by Hero of Alexandria". Let's set up a block and tackle to lift these loads.
A good sentence for the word block and tackle is............The sailors had to block and tackle in order to left the heavy dead body and treasure chest's.
A block and tackle pulley system consists of one fixed pulley and one moving pulley working together to lift heavy loads with less effort. For example, a flagpole typically uses a block and tackle pulley system to raise and lower the flag.
The mechanical advantage of a block and tackle system is calculated by counting the number of ropes supporting the weight being lifted. The formula for mechanical advantage in a block and tackle system is equal to the number of ropes supporting the load. For example, if a block and tackle system has 4 ropes supporting the load, then the mechanical advantage is 4. This means that the system can lift a load 4 times heavier than the input force applied.
A block is used to allow your team to score. A tackle is used to stop someone from scoring.

A block and tackle magnifies the pulling force applied to rope. This is useful for moving heavy objects, lifting heavy objects, etc. A good Example is all the old sailing ships like in The movies "Pirates of the Caribbean" used block and tackle to move and trim the sails. This is still in use by window washers on skyscrapers to exercise machines.
No, a block and tackle is not considered a wheel and axle system. It is considered a type of pulley system.
The cast of Block and Tackle - 1932 includes: Pete Smith as Narrator
A block and tackle is a system of two or more pulleys each enclosed by a housing with a rope or cable threaded between them.
