A rod may freely rotate about an axis that is perpendicular to the plane of the page. The rod is divided into four sections of equal length of $0.2\,\text{m}$ each, and four forces are exerted on the rod, as shown in the figure. Frictional forces are considered negligible. Which of the following describes an additional torque that must be applied in order to keep the rod from rotating?

Question

A rod may freely rotate about an axis that is perpendicular to the plane of the page. The rod is divided into four sections of equal length of $0.2\,\text{m}$ each, and four forces are exerted on the rod, as shown in the figure. Frictional forces are considered negligible. Which of the following describes an additional torque that must be applied in order to keep the rod from rotating?(a) $18\,\text{N}\cdot\text{m}$ clockwise
, (b) $18\,\text{N}\cdot\text{m}$ counterclockwise
, (c) $50\,\text{N}\cdot\text{m}$ clockwise
, (d) $50\,\text{N}\cdot\text{m}$ counterclockwise
