Question

The figure below shows a horizontal rod, of length 6.4 m, with forces acting on it. A 30 N force acts at its left end, point O, in a direction down and to the left, 45° below horizontal. A 25 N force acts at its center, point C, in a direction up and to the right, 30° to the right of vertical. A 20 N force acts at the right end, in a direction down and to the right, 20° below horizontal.

**Question: Net Torque Calculation**

Diagram Explanation:
- A horizontal rod labeled \(OC\) with \(O\) at the left end and \(C\) towards the right, measures 6.4 m.
- At point \(C\), there is a vertical line extending upward labeled with a 25 N force at a 30° angle from downward.
- At point \(O\), a 30 N force is applied downward at a 45° angle to the left.
- A 10 N force is applied at point \(C\) at a 20° angle downward to the right.
- There is a distance of 3.2 m indicated between \(O\) and \(C\).

Tasks:

**(a) Net Torque Around O**
What is the net torque (in N·m) on the rod about an axis through \(O\) perpendicular to the page?
- **Magnitude:** [Input box in N·m]
- **Direction:** [Select option for direction]

**(b) Net Torque Around C**
What is the net torque (in N·m) on the rod about an axis through \(C\) perpendicular to the page?
- **Magnitude:** [Input box in N·m]
- **Direction:** [Select option for direction]
