Three forces F, E, and F, ,act through the points with position vectors r, 1, and r, respectively, where 0 TADHIT L/.5TD 00H F = (3i – 2j - 4k)N, = (itk)m F, = (-i +j)N, , = (j + k}m F, = (-i+ 4k)N, (i +j +k)m (i) Show that this system does not reduce to a single force. When a fourth force F is added, the system of four forces is in cquilibrium. (ii) Show that F acts through the point with position vector (3k) m. 13 %3D %3D %3D
