Example 2.8


               There are three forces acts on a pulley as shown in figure below. By using Cartesian vector

               notation determine the magnitude and direction of the resultant force, FR.

                                                       Figure 2.23 (b)




               FR     = F1 + F2 + F3
               FR     = ΣFxi + ΣFyj
