Abstract
A method of inexpensive material tester is proposed for realizing an instrument based on the levitation mass method without the use of pneumatic linear bearings and a Zeeman type two frequency He-Ne laser. As an example a material tester using the pendulum, which evaluates the mechanical response of general objects against impact forces, is developed. The characteristics of the restoring force are determined using the same instrument under the free-swing condition without the object under test. To demonstrate the performance of the developed instrument, the impact response of a gel block is determined.
