Chapter 2.4, Problem 6SA

Now remove the sinusoidal load and add a 70 kg diver to the beam, balancing on the last 20 cm of the beam. You must add a force per unit length of $-g$ times $70/0.2\text{kg/m}$ to $f(x_i)$ for all $1.8\le x_i\le 2$, and solve the problem again with the optimal value of n found in Step 5. Plot the solution and find the deflection of the diving board at the free end.
