www.mapleprimes.comThis is the general equation for the transverse vibration of a uniform beam. beam varies harmonically with time, and can be written When a beam performs a normal mode of vibration the deflection at any point of the y = X (B, sin wt + B, cos wt), where X is a function of x which defines the beam shape of the normal mode of vibration. Hence d4X
