| Abstract: | This paper applies the Newmark's method to analyse the longitudinal and torsinal vibration of bars.After reduce the bar's free vibration differential equation to a lower order, we analogize it to the bending theory of the beam and gives an iterative procedure.The calculation illustrates that this method is very efficient to the estimation of the natural frequencies for the various shapes of bars. |
