It is more interesting to combine the Mechanics Diagram (Force guide diagram) with the common figure diagrams in life. In this paper, we will explain how to insert external pictures and text in mechanics diagram.One of the simplest mechanics diagrams is produced in Chapter 9.2. Many of our friends have questions, and the main questions are:
How to insert text next to a ball

Solution: As the question shows that this kind of relationship exists only between men and women, you can boldly split the diagram, because men must like women, however, women cannot have edges (like relationships ). Maximum Independent Subset = number of vertices-Maximum number of matching. Because it is a split-point
