For each situation below, determine the torque caused by the force F about the axis of rotation shown. The force in each case has a magnitude of 100 Newtons. We will use the common choice of a counterclockwise torque being positive and a clockwise torque being negative. Make sure that your sign is correct. 1. F 2.0 m 30° Is the torque clockwise or counter-clockwise? Check that the sign of your answer agrees with this. 2. 2.0 m Is the torque clockwise or counter-clockwise? Check that the sign of your answer agrees with this. 3. 2.0 m 90° Force acts % of the way along the bar. Is the torque clockwise or counter-clockwise? Check that the sign of your answer agrees with this.
