Categories: ,
The laboratory unit is designed to carry out laboratory experiments, determine frequencies and shapes of natural vibrations of a string, spreading rate of transverse wave in the string. 
 
The unit is performed as a basement with the following equipment installed on it: 
  • fixing upright intended for fixation of one end of the string;
  • exciter intended for exciting of transverse vibrations of the string in the vertical plane;
  • limiting upright for limiting the vibrating area of the string;
  • dynamometer measuring the tensile force of the string;
  • tension device intended for adjustment of the tensile force of the string.
Behind the string a horizontal measuring ruler with runner of a vertical ruler is installed. Low frequency generator with ‘accurate’ and ‘rough’ adjustments is used as the power source for the exciter.
 
Software and methodical documentation supplemented to the stand: methodical and technical documentation set intended for academic staff.
