A spool rests on a horizontal, frictionless surface and you are looking at it from the top view (appears as a circle). In the following questions, the spool is pulled by tension forces that are applied at various locations, directions, and radii. To solve each problem, draw the spool as a circle on a piece of paper and then draw the given tension vectors. REMEMBER that the direction UPWARD points to the TOP of the page and DOWNWARD points to the BOTTOM of the page. The resulting TORQUE will be either OUT OF the page (CCW motion, POSITIVE torque) or INTO the page (CW motion, NEGATIVE torque). A rope of tension 3T applies a force at radius 1R on the spool. It is located at 3 o'clock and pulls upward. What is the resulting torque in terms of RT? A rope of tension 4T applies a force at radius 2R on the spool. It is located at 6 o'clock and pulls to the left. What is the resulting torque in terms of RT? Rope #1 of tension 3T applies a force at radius 1R on the spool. It is located at 6 o'clock and pulls to the left. Rope #2 of tension 3T applies a force at radius 3R on the spool. It is located at 9 o'clock and pulls downward. What is the resulting torque due to both ropes in terms of RT?
