# Pre-Lab:The following figure is anairplane's view of a force table;a 120 gram masshangs off of pulley at 400. A second mass of 500 grams hangs off of anotherpulley at 205° according to the picture in Figure 6.1. The weights pull on thering in the center of the table via the pulleys.Picturein33A. Use vector components to find the combined total force (magnitude and direction)exerted on the ring by the two cables with weights hanging off of them.B. At what angle should a 3rd pulley be placed, and how much mass hanging off of it wouldbe needed to balance the system in part A so that the central ring does not move? fieureAirplane ViewForce TablePulley 1205°400Side ViewPulley 1Pulley 2CentralRingSide ViewPulley 2120grams500Airplane View of Force TablegramsFORCH FABLE/ouldFigure 6.1: Force Table
