For showing the conversion from electrical energy via mechanical, to potential energy by winding up a weight on a cord.
One end of the 6mm.
steel shaft carries an aluminium 'V' pulley 56 mm.
diameter, and the other end is fitted with a cord anchoring collar.
Supplied complete with driving belt.
This model uses the same basic assembly as the motor, but is mounted on a baseplate 230 x 90 mm approx.
which also carries a hand-drive pulley 120mm.
diameter coupled to the smaller dynamo pulley by a rubber belt to give a step-up ration.
Electrical output is via a pair of 4mm sockets.
The model may also be used as a motor on a 6-8 V D.C. supply.
Determination of charge on a electron by measuring a known distance on the basis of number of times of fall under gravity and of rise in uniform vertical electrostatic field in a series of charged oil drops.
To show the forces which can be exerted during thermal expansion or contraction.
Comprising a heavy cast iron frame 340x120x100mm with slotted end pillars to carry a stout iron bar.
The bar is threaded at one end for a large tensioning nut and has holes at the other end to accommodate the cast iron breaking bars.
Supplied complete with ten breaking bars.
