Forces and mechanics

Barton’s pendulums is a well known resonance effect but usually difficult to set up and store. This apparatus stores flat and can be quickly unfolded 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.

Product code: LA30-070

Visually and effectively demonstrate the relationship between temperature and pressure. The Digital Jolly Bulb is the perfect alternative to the traditional bulb and analogue gauge, pressures can be read directly from the built in digital display and the apparatus is sensitive enough to register an increase in pressure when the bulb is held gently in the hand.

This apparatus comprises a 1m long, 50mm diameter acrylic tube which can be partially evacuated using a hand pump through the end stopper.

For use in ‘g’ by free fall investigations with alternative lower sensors. The unit releases a ball bearing when the ‘ears’ are squeezed together. Connection is by standard 4mm leads.
