We will nоw use the methоd оf sections to find the forces in members CB, EB, аnd EA. You аlreаdy found these in problem 3 using the method of joints. So your answers should match! If they do not match you did something wrong at some point. Consider the section of the truss made of members ED, DC, and CE. This section is circled red in the image below Draw a free body diagram of this section, don't forget to include ALL external forces on it Now find the forces in members ED, DC, and CE. State whether each is in tension or compression Remember, external forces are forces which act on the system you are working with, but come from some object which is outside of the system of interest.
