| Abstract: | The constraint force of the spindle in uniform mass distribution rod of fixed axis rotation is analysed in gravity field,and the quantified relationship between the magnitude and direction of constraint force and the oscillation angle and oscillation length is given.The relationship graph between them is given by Matlab.It is visual for the cognition of the variable force nature of the constraint. |
