About this Simulation

This simulation models a pulley system with adjustable rope tensions created by attached masses. Learners can manipulate mass values and rope positions to explore how forces at different distances from the pivot create turning effects. The visualization shows real-time moment calculations and equilibrium conditions.

Learning objectives: Understand how moment (torque) depends on both force magnitude and perpendicular distance from the pivot | Investigate the conditions required for rotational balance on a pulley system | Predict and verify the relationship between masses and rope positions for equilibrium
