Question

If only 3 forces meet at a point in truss and if two forces are in the same straight line the force in the third member will be

Answer 1

Answer:

force acting on body directly

Explanation:

1) the force acting on the body is equal

2) the line of action of this force is parallel to each other

3) the line of action of this forces meet In a point

Answer 2

If only 3 forces meet at a point in the truss and if two forces are in the same straight line the force in the third member will be Zero.

Explanation:

When two forces among the 3 forces acting at the truss joint are collinear, The third force must be zero as there exists no force or reaction at that joint.
