Three identical massless rods are each acted on by two or more forces, all perpendicular to the rods and all equal in magnitude (with a force of magnitude F). None of these rods is in static equilibrium. Now imagine that you can add an additional force of magnitude F on each rod. Which of the rods can be brought into static equilibrium?

a. Rod 1

b. Rod 2

c. Rod 3

d. All of these rods can be in static equilibrium if one adds a force F in the appropriate place for each rod.

Answer:

d. All of these rods can be in static equilibrium if one adds a force F in the appropriate place for each rod.

Explanation:

Static equilibrium is achieved if the net forces acting on each rod equates to zero. The additional force if added at the appropriate places can bring the rods to static equilibrium if the resulting net forces equate to zero.
