Pendul reversibel, Kater´s

• Measurement of periods of oscillation of Kater’s reversible pendulum for two fulcra
• Adjustment of Kater’s reversible pendulum for equal periods of oscillation
• Determination of acceleration due to gravity

Special form of physical pendulum for determining local acceleration due to gravity g. Pendulum rod with two fulcra plus one sliding and one fixed disc weight for adjusting the period of oscillation. When correctly adjusted, the pendulum will oscillate about both fulcra with the same period of oscillation. The pendulum rod exhibits particularly low friction and is suspended in a stable frame. In order to adjust orientation, the support is equipped with two adjustment screws and a spirit level. Includes mounting plate for light barrier.
Height of apparatus with pendulum:      1.25 m approx.
Length of pendulum rod:   1.2 m
Separation of bearing points:       800 mm
Period of adjusted pendulum:      1794 ms when g = 9.81 m/s²
Total weight: 6.3 kg approx.
