Determine how much the bar will deflect at various points along its length under the loading shown below (assume weight of the bar is negligible). write a Matlab program to be able to solve for variable element numbers. Then use 10 elements (11 nodes) to find the displacements of the middle point of the structure (x=L/2) and end point (x=L). Repeat the same calculations for 20 elements (21 nodes). Compare the results and discuss the accuracy of the calculation compared to the analytical solution?
