Question

Every point on the force vector which is the internal force is having the same magnitude and the same direction as the whole force vector have.

(a) True

(b) False

The question was posed to me in an interview.

The origin of the question is Internal Forces Developed in Structural Members topic in division Internal Forces of Engineering Mechanics

Answer 1

Correct answer is (b) False

Explanation: The vector is made by joining the final and the starting point of the internal force. If we consider any arbitrary point then the length would be calculated w.r.t the starting point, which might give different magnitude but same direction. Thus the answer is false.
