Compound Atwood’s Machine Experiment | Mechanical Advantage & Acceleration Explained

How can a smaller mass support a larger load? In this practical physics investigation, we explore the fascinating behaviour of the Compound Atwood’s Machine, a two-pulley system that demonstrates mechanical advantage, force balance, and acceleration. Using a Data Harvest Light Gate, pulleys, masses, and EasySense software, we investigate how changing the distribution of mass affects the acceleration of the system. By plotting acceleration against the theoretical mass ratio, we can test whether the results follow the predicted relationship and even obtain an experimental value for g (acceleration due to gravity).
