SUMMARY

In mechanical systems, a 2-force member must have collinear forces to maintain static equilibrium, allowing it to exist in either tension or compression. However, a 3-force member does not necessarily require all forces to be collinear. The behavior of a 3-force member can vary significantly, making it a more complex scenario than that of a 2-force member.

2 force members have to be collinear, is that the same way with 3 force members? Just a curious question.

For mechanical systems in static equilibrium, a 2-force member has collinear forces. A 2-force member can be in a state anywhere between tension and compression. A 3-force member is another animal.
