Four forces Fsub1 , Fsub2, Fsub3, Fsub4 act on a particle in 2-space. The particle is in static equilibrium.
Fsub1 has magnitude 75N and points due east.
Fsub2 has magnitude 50N and points 30 degress north of east.
Fsub3 has magnitude 40N and points 60 degrees west of north.
Find the magnitude and direction of Fsub4.
Thank you very much.
