Authoritative PPT Summary
"Fixed Pulleys and Moving Pulleys" Tools and Machinery PPT Download
Part One Content: Exploring New Lessons
(1) The pulley on the top of the flagpole
A pulley that rotates in one position and does not move, like the pulley on the top of a flagpole, is called a fixed pulley.
What we found:
When a fixed pulley lifts a heavy object, downward force is required, indicating that the fixed pulley can change the direction of the force.
Summary: Fixed pulleys can change the direction of force, but they cannot save effort.
(2) Moving pulleys
The pulley on the hook of a tower crane that can move with the weight is called a movable pulley.
Summary: Moving pulleys can save effort, but they cannot change the direction of force.
What are the differences between fixed pulleys and movable pulleys?
Fixed pulleys do not save effort, but they can change the direction of force.
Moving the pulley saves effort, but it cannot change the direction of the force.
Fixed pulley and movable pulley PPT, part 2: expansion and extension
The fixed pulley is actually an equal-arm lever, and the power arm and resistance arm are equal to the radius of the pulley. According to the lever balance condition, it can also be concluded that the fixed pulley does not save effort and distance.
According to records, paintings about pulleys first appeared in an Assyrian relief from the 8th century BC. This relief shows a very simple pulley that can only change the direction of rotation. Its main purpose is to facilitate the giving of gifts. In China, drawings of pulley devices first appeared on portrait bricks and pottery well molds in the Han Dynasty.
Fixed pulley and movable pulley PPT, part three: summary of this lesson
The fixed pulley is fixed in one position and cannot move with the movement of the weight. It can change the direction of the force, but it cannot save effort; the movable pulley is not fixed and moves with the movement of the weight. It cannot change the direction of the force, but it can save effort.
