Abstract
Apparatus and method of determining the mass of an article by the shift of the period of oscillation of a flexibly mounted platform. An article whose mass is to be determined is placed upon the platform. The platform is caused to oscillate and the period of harmonic motion is calibrated. This period is compared against the period of harmonic motion when there is no article upon the platform, and the difference, or shift, in frequency, allows a determination of the mass of the article.
