The figure below has eight forces written on a Cartesian plane. The distance in each grid is 1 cm. The angle of each vectors are written in the table. In your solution, you will only use the forces assigned to you. Magnitude of forces F1=1 N, F2=2 N, F3=3 N, F4 =4 N, Fs=5 N, F6=6 N, F=7 N, F3=8 N. Required: 1. Replace the assigned forces by a single force R at the rotation axis O.
