1). the force of 12gf causes a clockwise moment.
2). Clockwise moment = 12×10gf
cm=120gf cm
Anti clockwise moment= 20×6=120gf cm
: Clockwise moment=Anti clockwise moment
: the rod is equilibrium.
3).if the direction of 20gf force is reversed, it will also create a clockwise moment.
resultant moment=(120+120)gf cm
(clockwise)
= 240 gf cm
