Centrifugal force kit HG0093
Gyroscope - demonstration model HG0094 The gyroscope model demonstrates the conservation of the orientation of its axis of rotation when no moments of external forces are present. It also shows the gyroscope’s reaction to a nonzero moment of an external force. The device is made of a metal circle placed on a steel axis with horizontal holes for threading a string used to set the circle rotating by pulling. The axis has two adjustable tapered roller bearings. In the set there are also two stands with support arms. One allows the gyroscope to rotate around the vertical axis, the other allows a tilt. Also, the string with a T-handle is included. • 4 elements: gyroscope 10,7 x 10 x 17 cm, D 10 cm, weight 175 g; 2 stands, string 60 cm with a handle; • materials: metal, plastic OSCILLATINGMOTION
the processes taking place in a washing machine while spinning wet clothes (spin dryer), simulate a lab centrifuge (centrifugal separator), demonstrate directly how centrifugal force works (Watt regulator with a shutter valve in cross section). • 5 elements: centrifugal apparatus, 2 test tubes with caps, Watt regulator with a shutter valve model, centrifuge; • dim.: 23,5 x 11,5 x 47,5 cm
A centrifuge can be used in physical experiments. Combined with other sets, it may come useful in experiments in acoustics or thermodynamics. The rotational velocity of the spindle depends on the velocity of the manually-powered pulley wheel. The machine can be used both vertically and horizontally. The kit helps explain
