  1. ANNOUNCEMENTS

  2. 1 of 3 A force is applied to the end of a straight wrench in order to rotate about the hex bolt. Which of the forces shown maximizes the torque applied to the wrench? 3 2 4 1 5

  3. 2 of 3 A force is applied to the end of a weird “L-shaped” wrench in order to rotate about the hex bolt. Which of the forces shown maximizes the torque applied to the wrench? 3 2 4 5 1

  4. 3 of 3 Bars A and B are acted upon by the forces shown. All forces have the same magnitude and are perpendicular to the bars. Each bar can rotate about its center on a frictionless pivot. The magnitude of bar B’s angular acceleration will be Greater than that of bar A. Equal to that of bar A. Less than that of bar A. Zero. A B LOOKING DOWN FROM ABOVE
