I need the answer as soon as possible
The magnitude of the vertical force W is 160 N. The direction cosines of the position vector from
A to B are cosb, = 0.500, cos0, -0.866, cose, -0, and the direction cosines of the position vector
from B to C are cose, = 0.707, cose, = 0.619, cost, = -0.342. Point G is the midpoint of the line
from B to C.
