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.
Represents internal structure and operating principles of an air cooled two-stroke engine.
All parts in aluminium alloy.
Ignition is shown by means of a miniature bulb.
Carburetter and fuel supply also sectioned. Mounted on base with printed diagram showing working.
Two-Stroke Petrol Engine Four-Stroke Petrol Engine are also available.
For use as a water turbine to drive a generator producing electricity or for use as a pump driven by a motor and raising a head of water to produce potential energy.
The rotor has eight 'bucket' blades and is housed in a block turbine chamber with a clear Perspex front.
Two inlet tubules (for turbine and pump operation respectively) and one outlet tubule are provided and the shaft carries a 15 mm.
diameter pulley.
With driving belt.
For showing potential energy in a wound-up spring and its conversion to electrical energy by driving a dynamo and lighting a lamp.
May also be used to wind up a weight on a cord showing the change from potential energy to kinetic and back to potential in the raised weight.
The steel shaft carries a clock spring with a free wheel device and winding ratchet, also an aluminium 'V' pulley 56 mm.
diameter.
One end of the shaft overhangs the base for use as line shaft when winding up a weight.
Dimensions 220 x 100 x 100 mm.
high Supplied complete with driving belt.
For use with motor/generator to give an indication of their output when used as dynamos.
The lamp-holders are connected in parallel.
Supplied with three lamps 3.5 V 0.25 A, M.E.S.
Operation of a commercial steam engine is well illustrated with this working model.
