"Fixed Pulley and Moving Pulley" Tools and Machinery PPT

Part One: The Pulley on the Top of the Flagpole

Let's simulate the flag-raising mechanism and study 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.

When we use a fixed pulley to raise the flag, in what direction do we need to exert force? What does this mean about the fixed pulley?

Fixed pulley can change the direction of force

When using fixed pulleys to lift heavy objects, do fixed pulleys have a labor-saving effect? How do we study it?

Use an iron stand as a support, install a fixed pulley, and put a rope on the fixed pulley.

Hang some hook codes at both ends of the rope and observe the status of the fixed pulley.

Record the experimental data.

Fixed pulley and movable pulley PPT, part 2: moving pulley

The pulley on the hook of a tower crane that can move with the weight is called a movable pulley.

Assemble a moving pulley experimental device and use it to lift heavy objects. Measure how much force was used, record and analyze the data to see what the moving pulley does.

Moving pulleys can save effort, but they cannot change the direction of force.

Think about it, under what circumstances do we use fixed pulleys and under what circumstances do we use movable pulleys?
