1 LASCELLS BARTONS PENDULUMS This Barton’s Pendulums apparatus provides a demonstration of a well known resonance effect. Traditionally, the apparatus is usually difficult to set up and store, but this version from Lascells stores flat and can be quickly unfolded and working to show the resonance between similar length pendulums. Once the demonstration is over it can be closed up again, to safely store the pendulum arrangement until required again. Dimensions: 350 × 300 × 60 mm. Weight: 1.4kg. Cat No. Description Price Per FMF-535-100 Bartons Pendulums 86.22 ea. 2 LASCELLS DOUBLE COMPOUND PENDULUM This apparatus provides a dramatic demonstration of physical pendulum behaviour. For small amplitudes of oscillation the pendulum exhibits predictable behaviour; however for large amplitudes the motion is chaotic. Students will be amazed at the apparent random oscillation and that the motion is different every time. In addition the apparatus may be locked in two positions giving two different length physical pendula. The variation in period between the physical pendulum and an approximated simple pendulum can be demonstrated. From the given data of mass distribution the centre of oscillation may be determined and therefore a value for g may be found. Cat No. Description Price Per FMF-335-100 Double Compound Pendulum 46.33 ea. 3 PENDULUM BALLS A range of pendulums, each consisting of a solid metal sphere with an attached hook.
