Abstract : The upper and lower bounds to frequencies of bending vibration of a rotating uniform beam simply supported at one end and free at the other are presented. The upper bounds were obtained by use of the Rayleigh-Ritz procedure using two different sets of trial vectors. The lower bounds were obtained using two methods: (1) The method of sums of resolvable operators and (2) The method of intermediate problems with truncation. The virtues of these methods are discussed in the text. (Author)
