Question 1 a) What are the steps involved in Finite element analysis? b) Attempt to formulate a mathematical model of a steel electric distribution pole.Write the Matlab code for solving the problem. c) Carefully study the spring system shown below. Solve the problem using direct stiffness method. ko FC - 4, 4540 Ribar

Answer 1

1.The steps involved for this problem in finite element analysis are :

Step 1 = first using the total potential energy formulae to solve the problem

Total potential energy = $\pi$ = U + WP

where U = free stream velocity = $\sigma \epsilon \nu$ / 2

WP = work potential = - ( f u )

Step 2 = on substituting the values and solving you will gsorry i et a equation

Apply principle of minimum potential energy = $\partial \pi$ / $\partial$ ui = 0 ,i= 1,2,3......

Step 3 = on partial differentiation you will get the required solution and values,arrange them in matrix form.

2.Sorry i don't know how to write a MATLAB code.

3.Sorry the values are not that clear to understand,so im giving solution for the same spring system with different values.(this solutionn will surely help you).
