What kind of pulley is picturedabove? How did you know?
Fixed Pulley– the pulley is attached to the ceiling
Moveable Pulley – the pulley moves on the string
Identify the pulley pictured aboveand give an advantage of using this
type of pulley.
It’s a fixed pulley and it changesthe direction that you lift the load
When using a fixed pulley, the amount of force _____ and the
direction the load moves _______.
Force stays the sameDirection the load moves changes
When using a moveable pulley, theamount of force _____ and the
direction the load moves _____.
Force decreases Direction the load moves stays the same
Which pulley system pictured above would require the least amount of
force to lift the load? Explain
