Five forces act on an object.
(1) 57 N at 90°
(2) 40 N at 0°
(3) 77 N at 270°
(4) 40 N at 180°
(5) 50 N at 60°
What are the magnitude and direction of a sixth force that would produce equilibrium?

  • physics -

    F1+F2+F3+F4+F5+F6 = 0
    i57+40-i77-40+50*cos60+i50*sin60+F6=0

    The student can finish this problem by
    using the same procedure as the previous
    problem.
