Two forces F1 and F2 are acting on a rod abc as shown in the figure. Select correct statement(s).

Q: Two forces F1 and F2 are acting on a rod abc as shown in the figure. Select correct statement(s). [τa means τnet about a]

Numerical

(a) If F1 ≠ F2 , then τa ≠ τb ≠ τc

(b) If F1 ≠ F2 , then τa = τb ≠ τc

(c) If F1 = F2 , then τa = τb = τc

(d) If F1 = F2 , then τa = τb ≠ τc

Ans: (a) , (c)
Sol: When the net force on a rigid body is zero, then the summation of moments about any point is constant.
