011 Resultant of three forces acting in a ring Jhun Vert Sat, 04/18/2020 - 03:41 pm

Problem 011
Three ropes are tied to a small metal ring. At the end of each rope three students are pulling, each trying to move the ring in their direction. If we look down from above, the forces and directions they are applying are shown in Fig. P-011. Find the net force on the ring due to the three applied forces.
