In this activity, you will study the behaviour of several driven oscillators during resonance.
In Experiment 1, you will cause a hacksaw blade to oscillate by magnetic force.
In Experiment 2, you will set up a Barton pendulum. It consists of several paper pendulum linked to a brass pendulum.
In Experiment 3, you will cause a hacksaw blade with a movable mass to oscillate by a massive pendulum.
