Problem 6: Consider a bar, of length 5.5 m, shown in the figure, is constrained to locate about its left end. In addition to the force exerted at the left end responsible for this constraint, three forces are acting on the bar that generate torques. The magnitudes of the first two forces are 24 N and 37 N, and the first force is acting on the end of the bar at an angle of 48° as shown. F3 F1 F2 Part (a) What is the torque, in newton-meters, due to F1 on this bar relative to the left end? Use a coordinate system with positive directed out of the screen. T1 =
