This GUI provides vibration output with plot and equation. You can change input parameters as you want. This program is graphically able to describe most of the single degree of freedom system. It is also designed to solve both free and force response systems such as undamp, overdamp, critical damp, and underdamp. Furthermore, the GUI produces the result from the free response and harmonic, resonance, base excitation, impulse, and unit function of force response. In addition, it can show plot of displacement and equation of final solution by text form. This program is mathematically based on 'Engineering Vibration 3rd edition, Daniel J. Inman'.
