(18) Two equal magnitude horizontal forces act on an instance, one force is pointing towards east and the other one is acting towards west. object but with opposite direction. For a) Is the object accelerated? Explain. b) Can the object be moving? Explain.
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...

Find the moment of the couple formed by the two forces (a) by resolving each force into horizontal and vertical components and adding the moments of the two resulting couples, (b) by using the perpendicular distance between the two forces, (c) and by summing the moments of the two forces about the pin. (Your answers need to be the same to all three.) (d) Why is your answer not equal to 100 2? 100 lb 4 3 2 in 5...
