Question : 41
Total: 78
Is the rod in equilibrium?
Solution:
Clockwise moment of force
= 12 gf × 10 cm
= 120 gf − cm
Anticlockwise moment of force
= 20 gf × 6 cm
= 120 gf − cm
since, the clockwise moment of force is equal to the anticlockwise moment of force, the rod is in equilibrium
Thus, Yes, the rod is in equilibrium.
Anticlockwise moment of force
since, the clockwise moment of force is equal to the anticlockwise moment of force, the rod is in equilibrium
Thus, Yes, the rod is in equilibrium.
