Two forces equal in magnitude and opposite in direction, acting on an object at two different points, form what is called a couple. Two antiparallel forces with equal magnitudes_1 = F_2 =7.90 N are applied to a rod as shown in the figure (Figure1). What should the distance l between the forces be if they are to provide a net torque of 5.20 N m about the left end of the rod? Is the sense of this torque clockwise or...

As you will see in a later chapter, forces are vector quantities, and the total force on an object is the vector sum of all forces acting on it. In the figure below, a force F1 of magnitude 6.10 units acts on an object at the origin in a direction θ = 35.0° above the positive x-axis. A second force F2 of magnitude 5.00 units acts on the object in the direction of the positive y-axis. Find graphically the magnitude...
