A truss is facing a two force member and both of them are in the opposite directions. And the truss is in equilibrium. And both of them are getting away from each other.The forces are called?

(a) Compressive forces

(b) Tensile Forces

(c) Parallel and collinear forces with same direction of heading

(d) The rotational forces

The question was asked in an interview for job.

The doubt is from Simple Trusses topic in portion Structural Analysis of Engineering Mechanics

Best answer
Right option is (b) Tensile Forces

The best explanation: 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.
