Mechanical vibration is a form of oscillatory motion of a solid, a structure, a machine, or a vehicle induced by mechanical means. Differential equations, taken after calculus 3, is a more advanced mathematics course required by some civil engineering programs. It is observed that adding magnetic field makes the temperature gradient reduce due to domination of conduction mechanism in high Hartmann number. Obtained results have been validated by several examples. In addition, we have addressed the computational costs. discuss about how to solve differential equations by using Laplace Transform. In this section, we look at how this works for systems of an object with mass attached to a vertical spring and an electric circuit containing a resistor, an inductor, and a capacitor connected in series. Even a little increment of the ratio may cause higher variance between considering and not considering the rotary mass moment of inertia, especially for the high natural frequency. Models such as these are executed to estimate other more complex situations.
