(7%) Problem 4: Consider a bar, of length 4.5 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 28 N and 38 N, and the first force is acting on the end of the bar at an angle of 25° as shown. o F₁ F₂ 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 A 33% Part (a) the screen. A 33% Part (b) What is the torque, in newton-meters, due to F₂ on this bar relative to the left end, if this force is acting at the midpoint of the bar? Us coordinate system with positive directed out of the screen. A 33% Part (c) What is the magnitude of the force F3, in newtons, if the force is a distance 0.55 m from the left end and the bar is not rotating?
