### Approach
- Using the membrane_solution function, a vector of the displacements is formed
- Next, the average displacement for each element is calculated. For each elements, the dispalcement at all four courners is taken and then averaged
- Using these values, the work done by pressure can be calculated
- For the change in dispalcement over the x and y coordinate system, the values of the change on the left and right (y-axis) or top and bottom (x-axis) are taken and averaged
- Using these values, the strain enegery can be calculated

### Approach
- This problem uses the bisect method for locating roots and the SE_diff function for calculating the difference in work and strain energy of the membrane
- The script runs through all iterations of different amounts of nodes, zeroing the SE_diff function output and saving the values for tension in the T variable as a vector

### Approach
- This script uses the tension_sol function as described in the part above, running though all iterations of pressure
- Additionally, the max deflection for each pressure and tension is calculated at each iteration
- From there, a general linear regression is calculated with the formula P(x) = A*w^3
- The results are plotted
