Which of the following sets of concurrent forces may be in equilibrium?
Options
- A(F₁=3 ~N , F₂=5 ~N , F₃=10 ~N )
- B(F₁=3 ~N , F₂=5 ~N , F₃=9 ~N )
- C(F₁=3 ~N , F₂=5 ~N , F₃=6 ~N )
- D(F₁=3 ~N , F₂=5 ~N , F₃=15 ~N )
Correct answer
C. (F₁=3 ~N , F₂=5 ~N , F₃=6 ~N )
Step-by-step solution
According to triangle law of forces, resultant of two forces must be greater than or equal to the third force. In option (a), (F₁(3 ~N )+F₃(1 ~N ) F₃(6 ~N ) ) Hence, these sets of concurrent forces may be in equilibrium. In option (d), (F₁(3 ~N )+F₂(5 ~N ) < F₃(15 ~N ) ) Hence, these sets of concurrent forces may not in equilibrium.
