Pulley Mechanics Lab

1

⚙️ Choose Pulleys

Select 1 (fixed), 2 (moveable), or 4 (compound) pulleys. More pulleys = less force needed!

2

⚖️ Adjust Weight

Use sliders to change the load weight, friction, and applied force. Watch the math update!

3

🏋️ Lift the Load

Hold the green LIFT button or press SPACE to raise the load. See pulleys rotate!
