Randall D. Knight — Force and Motion: Problem 20

Exercises 20 through 22 show a free-body diagram. For each, write a short description of a real object for which this would be the correct free-body diagram. Use Examples 5.4, 5.5, and 5.6 as examples of what a description should be like. Exercise 20 depicts an object with an upward tension force \( \vec{T} \) and a downward gravitational force \( \vec{F}_G \), with a noted net force \( \vec{F}_{net} = 0 \).
