c. A third force is added as shown (perpendicular, midway F3 between the left end and Fa) to keep the rod from rotating F 2 What must the magnitude of this force be? Created by Alexandru Maries 9-5 Tutorial: Torque and statics IV. Torque for non-perpendicular forces: 1 = FYperpendicular I= Fr. where F = force di = perpendicular distance from the point of rotation to the line along which the force is applied wer sin 8 These two approaches are complementary. Depending on what's given, sometimes using FIT is more convenient, other times using Fri. A. In the situation shown, the rod (length 2.0 m) can rotate about its 30 midpoint. Fi = 10 N, F2 - 20 N. Which approach is more convenient to use to calculate the net torque in this situation? at = Fir b. T= Fr c. There's no advantage to picking one or the other. The torque caused by this force around the middle of the rod is (circle one): negative zero positive B. Use the approach you identified to calculate the net torque acting on the rod. Iculate the torque caused
