The governing differential equations for vibration of the ABH beam is first converted into … Webx)y= 0 solve the wave equation. It is simple to verify that these are functions of the form y(x;t) = f(x vt): Since the wave equation is linear, superpositions of solutions to the wave equation are also solutions to the wave equation. The general solution is of the form f(x vt) + g(x+ vt) for arbitrary functions fand g. [1] Problem 1.
