The figure below shows a horizontal rod, of length 7.4 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
The figure below shows a horizontal rod, of length 7.4 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.
 
*a) What is the net torque (in N · m) on the rod about an axis through O perpendicular to the page?
magnitude=  ____N · m
direction= clockwise or counter clockwise
 
(b)What is the net torque (in N · m) on the rod about an axis through C perpendicular to the page?
