A surface that re-directs force using a rope is called?
pulley
How is a flagpole a pulley system?
When you pull up the flag you pull it up by the rope. The rope has a pulley on it. So the actual poll is not a pulley but it has a pulley system on it
What kind of rope is used in a fixed pulley?
A single continuous rope that is known as block and tackle is used. A fixed pulley changes the direction of the force on a belt or rope.
What does a pulley do with force?
A pulley directs the force in a rope into a new direction.
What is the mechanical advantage of a combined pulley?
A ratio that is the number of falls of rope in the system, apart from the rope between head-pulley and winch or you.
What is the part of a rope called from the pulley to the effort?
Effort Arm
The place on a pulley in which the rope lies?
grooves
The part of a rope from the pulley to the effort is called an?
effort arm
What pulley raises sails on boats?
A pulley doesn't raise or hoist sails. A pulley is just a wheel that eases a change in direction of a rope. It is a rope that hoists or raises sails. A rope for this purpose is called a Halyard.
A surface that re-directs force using a rope is called?
pulley
A simple machine that has a wheel with a groove and a rope to pull?
This is called a pulley.
What is the simple machine used to hoist the flag?
Rope and pulley.
Explain what a sheave wheel is and what it does?
A sheave or pulley wheel is a grooved wheel often used for holding a belt, wire rope, or rope and incorporated into a pulley. The sheave spins on an axle or bearing inside the frame of the pulley. This allows the wire or rope to move freely, minimizing friction and wear on the cable. (A sheave is actually part of the pulley system.)

What does which and sheave do?
A sheave (/ʃiːv/) or pulley wheel is a grooved wheel often used for holding a belt, wire rope, or rope and incorporated into a pulley. This allows the wire or rope to move freely, minimizing friction and wear on the cable. Sheaves can be used to redirect a cable or rope, lift loads, and transmit power. A sheave (pronounced “shiv”) is actually part of the pulley system. The sheave is the rotating, grooved wheel inside the pulley.

What is a simple machine made of a wheel and a cord called?
That would most likely be a pulley. A pulley is essentially a wheel on an axle that usually has a groove in the middle of its circumference that holds a rope, cable, belt, or chain. Pulleys are used to transmit motion rotationally and apply force in the direction of said motion. Two or more pulleys makes a tackle. Hope this is what you were looking for.
