Concave transparent acrylic body with spherical curvature. A rolling ball oscillates inside the concavity about its rest position like a mathematical pendulum does. The radius of curvature is equivalent to the length of a normal pendulum. Includes three steel balls. Diameter of balls: 16 mm Radius of curvature: 200 mm Diameter: 140 mm

Symmetrical pendulum system on an axle, for demonstrating centrifugal force. The pendulum arms are held in a state of rest by a coil spring. Depending on the rotational speed, they are lifted against the force of gravity as the axle turns. This can then be used to control the speed of a steam engine. Rotation […]

Spoked wheel with large moment of inertia for demonstrating the conversion of energy in the conversion of kinetic energy to potential energy and vice versa. Includes suspending rod and adjustable suspension mechanism. The rotating axle is held in a horizontal position by two strings attached to a suspending rod and is moved upward by winding in […]

Gyroscope with low-profile, dynamically balanced metal rotor in a Cardan gimbal mount. Ideal for studying gyroscopic stability phenomena, precession and nutation. Also supplied is a pendulum mounting that can be used for investigating the rolling or tipping moment. The set includes plastic Cardan discs, Cardan gimbal mount, pendulum mounting and starting cord. Dimensions: 170×120 mm² […]

Sensor for triggering the 3B NETlog™ unit (U11300) or a digital counter (U8533341) in time measurements on moving objects. Suitable for opto electronic scanning of light and dark markings on moving objects or in conjunction with a reflecting foil to form a wide spaced obstruction sensor. The intensity of the laser beam is adjusted automatically […]

High quality precision-made gyroscope for demonstration as well as for quantitative determination of gyroscopic laws by means of practical experiments. Experiment apparatus with a shaft that can be tilted and rotated while attached to a stand rod. On one side of the shaft there is a disc mounted on dual ball bearings, while on the […]

Experiment motor for universal use in experiments on rotational motion, e.g. for experiments using the Watt’s governor (P-1009695). Can also be used as a generator in conjunction with the included hand crank. Robust clockwise and counter-clockwise rotating IDC motor with epicyclic gearbox and quick-action chuck in a tough anodized aluminum casing with removable and adjust […]

Rotating apparatus for determining angular acceleration as a function of the torque and for determining the moment of inertia depending on mass and distance from an axis. An axle on agate bearings supports a cross bar to which weights can be attached. The force from a driving weight is conveyed to the axle via a […]

Anordning för undersökning av friktionsfri rotation. En liten roterande skiva med en gradskiva stödjer en tvärstång på vilken det går att fästa vikter. Skivan stödjs av en luftbädd och dess axel är centrerad i denna. En drivande vikt är upphängd på en krok i änden av en tråd som går över en enkel trissa på […]

Portable microprocessor-controlled device with quartz-controlled time base for observation of periodic movements, as well as for frequency and rotation speed measurement. Xenon flash tube built into a robust plastic casing with handle and photo thread for mounting on a stand, continuous frequency adjustment in two ranges through coarse and fine setting using control knobs, 4-digit […]
