Centrifugal power device with experimental trolley
Supplier: CORNELSEN EXPERIMENTA
With the equipment, centrifugal forces that arise during a body's rotation around a specific axis can be measured and examined. The device consists of a plane with a path for a cart. On the underside there is a vertical shaft that is mounted in a bearing. The plane is made to rotate with a laboratory motor connected with a drive belt to the bearing. The experimental trolley is placed on the track and prevented from leaving the track by two bent steel wires. A wire is connected to the trolley that runs over a pulley and on to a dynamometer.

Radiometer
Supplier: MOLLER THERM
Radiometer according to Crookés. Consists of a glass container on foot with low air pressure and needle-bearing spinner with four vertical mica discs. The discs are black on one side and shiny on the other. The discs thus absorb radiation differently. The higher temperature of the dark side means that the air molecules get greater kinetic energy in collision with the dark side of the discs than with their shiny side. The result is that the spinner starts to rotate.

Thermogenerator, peltier element
Supplier: CORNELSEN EXPERIMENTA
72 series-connected semiconductor elements, mounted between two ceramic plates which in turn are attached to heat-conducting metal. If the metals are exposed to different temperatures, a voltage arises, sufficient to drive, for example, a slightly rotating motor. The thermogenerator can also be run in the other direction, ie. a voltage is connected and a temperature difference is obtained across the metal legs.
