Problem
A horizontal rod is pivoted at its left end. Three forces of equal magnitude 5N act at the point 0.40m from the pivot.
A. Upward, perpendicular to the rod.
B. Parallel to the rod, directed away from the pivot.
C. Downward, perpendicular to the rod but applied at 0.20m from the pivot.
Identify which force produces zero torque about the pivot and state the reason in one sentence.
