The figure shows a meter stick, which can pivot about an axis indicated by the black dot (at 25 cm). The meter stick has a moment of inertia of 1.0 kg m2. Forces F1 = 1.3 N, F2 = 5.6 N, and F3 = 8.7 N act on the meter stick at the 0 cm, 70 cm, and 1 m marks, respectively, as shown. What is the net torque (in units of N m2) acting on the meter stick? You should use the convention that a counterclockwise torque is positive and a clockwise torque is negative.
