Let's say that the internal forces in members AB, BC, CA are F1, F2, and F3 respectively. Plot F1, F2, and F3 as a function of L where L varies from 1.0 to 3.0. Here are the steps you need to take: 1. Determine the angle BAC in terms of L first 2. Draw the free body diagram at B. This would expose F1 and F2 and would allow you to solve for F1 ad F2 in terms of L and the 84kN force 3. Draw the free body diagram at C and solve for F3 4. F1, F2, and F3 will come out to be functions of L. Create plots for these in python.
