A comprehensive set of mechanical vibration and wave motion apparatus based on a sturdy, reliable vibration generator that can be used with any frequency generator that can deliver a signal of up to 1A. The piston delivers an amplitude of up to 7 mm, depending on the load and frequency. The generator can be used on the bench or attached to stand material via a threaded socket on the bottom surface.
The accessories include a wire hoop and a set of vibrating metal strips for mechanical resonance studies as well as a spiral spring and an elastic cord for wave investigations
Package Dimensions 8.0 H x 14.0 L x 14.0 W (inches)
Package Weight 3.0 pounds
Country of Origin China
The vibration generator itself arrived OK but this is supposed to be a set which should include accessories. A wire hoop, a set of vibrating metal strips, a spiral spring, and an elastic cord SHOULD HAVE BEEN INCLUDED BUT WERE NOT IN THE PACKAGING. The only option I saw was to return it for a refund but it appears the price went up a little so, if I purchase a replacement which I will need to, it is going to cost me more and I will have to wait to get the replacement. This is a problem for me. I wish that I could contact Amazon directly and discuss options but there is no option to call someone directly. This is frustrating.The vibration generator itself is reasonably priced and feels solid (these a a common item in highs school and college physics labs) but it would help if the manufacturer included basic instructions with the unit.
