describe the force board experiment to show how to obtain the resultant of two nonparallel coplanar force acting at a point.four forces of magnitude 10N, 5N, 4N, AND 6N acts on an oblect in the direction north. West, east and south respectively.find the magnitude and direction of their resultant

X = hor = 4 + (5) = 1N.
Y = ver = 10 + (6)
R = sqrt(x^2+y^2) = sqrt(1+16) = 4.12
tanA = Y / X = 4 / 1 = 4,
A = 76 deg, CW = 18076 = 104 deg =
Direction.
