3. Consider the figure shown below.
a. Determine the horizontal displacement at point C in terms of Q, w, $L_1$, $L_2$, E, I, and/or A. Assume
E, A, and I are the same for both sections.
b. Thought exercise: How would you proceed if we were interested in the vertical displacement?
Comment on what obstacles exist for calculating this and/or what changes to your solution
strategy would be needed to enable you to solve this problem.
