Engineering Physics Annotation << Back Change of weight of airtight container with built-in electromechanical vibrator Dmitriev A.L. Nikushchenko E.M. Chesnokov N.N. Weight of airtight container about 1,1 kg with electromechanical vibrator built-in inside, with independent supply and contactless control, has been measured. Decrease of container weight up to 170 μg, basically, is determined by heating of copper wire of vibrator electromagnet and practically is not related to artifacts – change of buoyancy, air convection, electromagnetic interference. Key words: weight, oscillator, temperature, gravity mass. Contacts: E-mail: chesnokov@sartogosm.ru Pp. 28-30.
