Abstract :
Move the principle of the double pendulum, which is a harmonious motion around
the equilibrium point in the direction of a person shaking his head or swinging left
to right. Conduct two tests with pendulum load of 5 kg and 10 kg. Tool work
system that is a load mounted on the end of an iron arm with a mass of objects 5
kg and 10 kg. If the load is pulled to one side, then released, the load will swing
through the balance point to the other side. After the pendulum swings, the pulleys
that are connected to the generator rotate and produce electrical energy. The
prototype test results of the pendulum system power plant at each pull of 160 °,
145 ° and 130 ° angles are obtained with 4 swings. At each swing can produce
different voltages and currents. The average power produced by a 5 kg load is
smaller than that of a 10 kg load. The average power with the biggest 5 kg load is
2.21 watts, while the average power with the biggest 10 kg load is 4.10 watts.
