Torsion Pendulum (34600)
For the investigation of free rotary oscillations at different dampings (aperiodic, creeping and limit adjustment) and of forced oscillations (resonance curves, phase changes between exciter and resonator). Oscillation system consisting of ball-bearing wheel, which is connected to the driving rod via a spiral spring. Driven via eccentric by an electromotor with fine and coarse speed adjustment. Damping by electromagnetic eddy-current brake. With scale ring and pointers at exciter and resonator; can also be used for shadow projection. Includes electromotor mounted on base plate.
Natural frequency: 0.5 Hz approx. Exciter frequency: 0 to 1.3 Hz(continuously adjustable) Connections:Motor: 24 V d.c., 0.7 A,via 4-mm socketseddy-current brake: max. 2 A (appr. 15 V d.c.)via 4-mm sockets Dimensions: 40 cm x 14 cm x 27 cm Weight: 4 kg
Klinger Educational Products highly recommends as an additional method of conducting this experiment:The IR Position Detector (IRPD) which enables automatic measurement of the motion of the lead balls in the gravitation torsion balance. 332 11 IR position detector.
