Nov 16, 2013· After placing 4 colored sand piles on a steel pan, Mr. Kanazawa rubs the surface of the metal pan with a rubber ball attached to the tip of metal stick to generate the vibrations. The ball doesn't smoothly slide. Instead, it slips and sticks, slips and sticks, due to the friction, creating a strong vibration of particular frequency.

First, the APEX™ is a pocketsized vibration monitoring package that travels with maintenance crews and can be placed on any vibratory system to track vibrations, and more. Readings can be collected via a smartphone app, allowing technicians to view the equipment's realtime data for vibration, stroke, frequency, and more.
Sound and Vibration (15 ratings ) Share this activity . Sound is more than just noise it's energy. Airy whispers and earsplitting screeches all are forms of energy that cause physical objects to vibrate. Let your young scientist explore this new world of sound with an experiment that just requires a handful of common items.
Vibration Analysis extends our sense of touch by a few leaps. It detects and measures vibration movements in machineries that are too small for us to feel, then allows us to identify the sources of these vibrations, which are then categorized according to severity. Informed decisions can .
