SUMMARY
The discussion clarifies that a strut is classified as a two-force member, which implies that it experiences forces only at its two endpoints. The confusion arises regarding the absence of an equal and opposite force at point B (Fba) in calculations. It is established that Fba is indeed present but is considered an internal force and is not included in the free body diagram for the entire system, which consists of the bed contents and the strut.
PREREQUISITES
- Understanding of two-force member theory in statics
