torsional frequency meaning in Hindi

Standard test method for fundamental transverse , longitudinal , and torsional frequencies of concrete specimens
The torsional interaction from the electrical couplings among the generating sets is presented and the influence of the natural torsional frequency of the generating sets on the torsional oscillation characteristics is described . the torsional dynamics between identical parallel turbine - generators are deduced as well as that between non - identical parallel turbine - generators . then the basic principle of equivalent simplification of generating units for different operational condition is summarized
