Stage Two: Data Collection: To test the principles of mechanical advantage, they teammates worked together to construct a simple machine: a block-and-tackle pulley system designed to lift a specific lead weight a set distance off the deck.

The rig could be reconfigured to run a line through one to seven pulleys. An attached spring scale measured the force required to pull the line through these various configuration, thus lifting the weight.
