Simple Machines: Pulleys

single fixed pulley has the fulcrum between the force and the load
pulley a kind of lever that can change the direction of force and/or multiply
numbers of lines determines how much the force is amplified
block and tackle consists of a fixed and a movable pulley
movable pulley set up so the force and load move in the same direction
__can be set up in 3 ways: single fixed pulley, movable pulley, block and tackle pulley
in a pulley system, the effort__and effort __ movement are in the same direction force movement
in a block and tackle system, the effort force moves__as the load moves__ downward up
with the pulley system, the resistance__is in the direction of gravity, and the resistance__motion is the opposite direction force motion
with a movable pulley, the___is at the end of the lever where the supporting rope touches the pulley fulcrum
what does a movable pulley resemble a second class lever
what does a single fixed pulley behave like a first class lever
this type of pulley only changes the direction of the force single fixed pulley
