If two forces are in the opposite directions. And both of them are coming towards each other. And are collinear too. Then the truss is getting a compressive stress. As the forces are trying to decrease the length of the truss. Hence if the two force members are in such conditions the forces are compressive forces.

Introduction:
In the field of mechanical engineering and structural analysis, trusses are commonly used to support loads and distribute forces. Trusses are composed of interconnected members, and each member is subjected to internal forces. These internal forces can be either compressive or tensile, depending on the direction of the force relative to the member.
Explanation:
A truss member experiencing a two-force condition means that the member is only subjected to forces at its two ends, and these forces are acting along the axis of the member. In this scenario, if both forces are directed towards each other, it implies that the member is being compressed.
Compressive Forces:
Compressive forces are those forces that tend to compress or squeeze a material. When two forces are acting towards each other, they create a compressive force within the member. This compressive force is directed along the axis of the member and tends to shorten or compress the member.
Equilibrium:
For a truss member to be in equilibrium, the sum of all the forces acting on it must be zero. In the case of a two-force member, this means that the compressive force exerted by one end must be balanced by the equal and opposite compressive force exerted by the other end. This equilibrium condition ensures that the member remains stable and does not deform or collapse under the applied loads.
Significance of Compressive Forces:
Compressive forces play a crucial role in truss design and analysis. They help in transmitting the applied loads to the supports and other members of the truss structure. By resisting compression, truss members maintain their shape and structural integrity. The ability of a material or member to withstand compressive forces is determined by its compressive strength.
Conclusion:
In conclusion, when a truss member is facing a two-force condition with both forces in opposite directions and coming towards each other, the forces are compressive forces. These compressive forces are essential for maintaining the stability and integrity of the truss structure. Understanding the type and direction of internal forces in truss members is crucial for designing and analyzing structures to ensure their safe and efficient performance.
