Danish Instrument Inventory text:
Centrifugal machine. Mahogany table 900x630 on 3 turned mahogany legs. On a solid mahogany upright H1200 is mounted a mahogany drive wheel Dia400 on a horizontal axle. Cord drive to 2 vertical rotating axles on the table on which can be mounted different mechanisms to be rotated. These are:1: Mahogany board L760 with 2 ivory balls of different mass, connected by a cord and sliding on a brass rod; to demonstrate angular momentum.2: Mahogany board L760 with 2 ivory spheres of same mass, connected by a cord and sliding on a brass rod; to demonstrate angular momentum.3: Mahogany board L760 with 4 sloping glass tubes to contain fluids and solids floating or sinking in the fluid during rotation.4: Glass beaker, pear shaped Dia100 H150, closed by a sealed stopper. Contains mercury and water.5: Watt's centrifugal regulator. Brass.6: Mahogany board L760 on which a mass can move radially during rotation. A cord connects this to a mass moving vertically on an upright H400 at the centre of the rotation; its gravity will provide centripetal force for the radially moving mass.7: Glass beaker H160 on brass foot.8: Vertical, central iron rod with 4 steel springs forming a globe. The springs are fixed at the bottom, but can slide on the vertical rod at the top. For demonstration of the flattening at the poles of the earth due to the rotation.9: Square wooden frame with suspended ivory ball to demonstrate Foucault's pendulum.Not signedc1800 (g)
