Consists of two disks which can be loaded with up to 8 ball bearings in internal compartments. Load one disk symmetrically and the other non-symmetrically to show the difference. Instructions and eight solid balls included.
General purpose student bench meters with full-scale accuracy of ±2.5% and overload protection. Additional features: large 3" scale, external zero-adjust calibration, and fully enclosed plastic case with inclined meter face. Double range, 0-5 V (0.1 V)/0-15 V (0.3 V).
To show the conversion of mechanical energy into electrical energy. Turbine with transparent cover, inlet, and outlet tubes directly connected to a dynamo. Fitted on base.
Supertek's Wave Demonstrator is a 6-foot metal helical spring. This high-quality spring is ideal for demonstration of travers waves, wave propagation, wave reflection and standing waves. 20mmD.
Demonstrating longitudinal and transverse waves. Some eccentric discs move several metal rods. Transverse waves are obtained by straight rods and longitudinal waves by bent rods.
Nickel-plated steel weight with slot design ensures that it may be easily removed and replaced, but will not fall off accidentally. All weights have the same size slot. Will fit both 50g or 100g nickel plated steel weight handers.
