2. Basic Definitions Mathematical Model is a mathematical representation of the physical model through use of appropriate physical laws. Transfer Function of a system is defined as the ratio of Laplace Transform of output to the Laplace Transform of input with zero initial conditions. Transfer function can be mathematically represented as

3. Mechanical Translational System 3 The Model of a mechanical translational system can be obtained by 3 basic elements Mass : weight of the mechanical system is represented by mass and it is assumed to be concentrated at the center of the body Spring: Elastic deformation of the body can be represented by a spring Dashpot: The friction existing in the mechanical system is represented by dashpot. Dash pot is ideally a piston moving inside a cylinder with viscous fluid. The force acting on a mechanical body are governed by Newton’s second law of motion. i.e the sum of forces acting on a body is zero.
