The force in member ab is compressive, and it is not tension. Blog Post End. In the following case, continue writing the next sentences of long-form content. Do not write numbers or bullet points. I. What is the force in member ab, and is it tension or compression? II. The forces on members AB are not necessarily equal because of different lengths and angles between them as well as where the loads are located. VII. This means that when you calculate these forces by using formulas for both tensions (T) and compressions (C), then they will cancel out to zero because T=0+C=0; so this must be a compressive member with no net external load acting on it from any direction: T-C=0!
