FEA for Dynamic Problems

Finite element analysis or FEA is a computational tool that evaluates the approximate solution for a particular engineering problem. The tools provided by FEA help to evaluate the solutions of partial differential equations (PDEs) computationally following a numerical approach. Solutions of the PDEs can also be performed by following traditional algebraic approaches, but when the problem gets towards the complex side, it becomes very tedious and almost impossible to arrive at the solutions. In such cases, the FEA fulfills the purpose by evaluating the equations following multiple time steps and iterations. The more the time steps and iterations, the more accurate the solution. The solution plotted by FEA analysis and mathematical approaches varies asymptotically.

To measure g (the acceleration due to gravity) the following experi-ment is carried out. A ball is dropped from the top of a 30-m-tall building. As the object is falling down, its speed v is measured at various heights by sensors that are attached to the building. The data measured in the experi- ment is given in the table. 田田田田田田 x (m) 5 10 15 20 25 田田 v (m/s) 9.85 14.32 17.63 19.34 22.41 田田田田 In terms of the coordinates shown in the figure (positive down), the speed of the ball v as a function of the distance x is given by v? = 2gx. Using linear regression, determine the experimental value of g. Use 4 decimal places.
