If two forces are in the opposite directions. And are collinear too. Then the truss is getting a tensile stress. As the forces are trying to increase the length of the truss. Hence if the two force members are in such conditions the forces are tensile forces.

Introduction
In this question, we are given a truss that is in equilibrium and facing a two-force member. Both forces are in opposite directions and are getting away from each other. We need to identify the forces and determine the correct option among the given choices.
Explanation
To understand the correct answer, let's analyze the situation and the nature of the forces involved.
Definition of Equilibrium:
In mechanics, equilibrium refers to a state where all forces and torques acting on a body are balanced, resulting in zero net force and zero net torque. In simpler terms, the body remains at rest or moves with constant velocity.
Two-Force Member:
A two-force member is a structural element that is subjected to only two forces. These forces are equal in magnitude, opposite in direction, and act along the line of the member. Since the truss is facing a two-force member, we can assume that the forces acting on it are equal in magnitude and opposite in direction.
Opposite Directions and Getting Away:
The question states that both forces are in opposite directions and getting away from each other. This implies that the forces are pulling or stretching the truss in opposite directions.
Tensile Forces:
Tensile forces are forces that act to stretch or elongate an object. When a force is applied to an object in tension, it tends to pull the object apart. In this case, both forces acting on the truss are pulling it in opposite directions, causing it to stretch. Therefore, the correct answer is option 'B' - Tensile Forces.
Conclusion
In conclusion, when a truss is facing a two-force member and the forces are in opposite directions, getting away from each other, the forces are called tensile forces. Tensile forces act to stretch or elongate an object.
