Two forces are applied to a structure. F1 has a magnitude of 950 N and its direction makes angles of 45° with respect to the x-axis, 120° with respect to the y-axis, and 30° with respect to the z-axis. F2 is given as (10i -50j + 50k) N. Find the resultant vector R=F, +F, in terms of its rectangular components, find the magnitude of R, and determine the unit vector in the direction of R (R ).
