If a body is in equilibrium under the action of three non-parallel coplanar forces, the forces must be concurrent, that is, must meet at a single point. Specific examples are provided here to illustrate the validity of this statement by the use of free-body diagrams as well as during the discussion of equilibrium and moments. These cases are…

Presenting posters at scientific conferences is often viewed as a valuable way for professionals, researchers, and students to cultivate presentation skills.
