Problem: Three concurrent forces P, Q, and F have a resultant of 5 lb directed forward and up to the right at θx= 60°, θy = 60°, θz = 45°. P equals 20 lb and passes through the origin and the point (2, 1, 4). The value of Q is also 20 lb and it passes through the point (5, 2, 3). Determine the magnitude of the third force F and the angles it makes with the reference axes.
