Pulleys

This type of pulley has the fulcrum (axis of the pulley) between the force and the load.

• Complex pulley

• Single fixed pulley

• Movable pulley

• Block and tackle system

It is a kind of lever that can change the direction of the force and/or multiply the force.

• screw

• wheel and axle

• wedge

• pulley

It determines how much the force is amplified.

• The effort movement

• The number of lines

• The resistance force

• The load

This type of pulley consists of at least one fixed and one movable pulleys.

• Movable pulley

• Complex pulley

• Block and tackle system

• Single fixed pulley

The setup of this pulley makes the force and the load move in the same direction.

• Movable pulley

• Single fixed pulley

• Block and tackle system

• Compound pulley

_____ can be set up in three different ways: a single fixed pulley, a movable pulley or a block and tackle.

• Levers

• Pulleys

• Inclined planes

• Screws

In a pulley system, the effort _____ and effort _____ are in the same direction.

• stress, action

• fulcrum, load

• motion, resistance

• force, movement

In a block and tackle system, the effort force moves _____ as the load moves _____.

• downward, up

• sideways, down

• upward, sideways

• sideways, up

With the pulley system, the resistance _____ is in the direction of gravity, and the resistance _____ is in the opposite direction.

• movement, strength

• load, fulcrum

• force, motion

• lines, axis

With a movable pulley, the _____ is at the end of the lever where the supporting rope touches the pulley.

• resistance

• fulcrum

• load

• groove
