Three forces are acting on a column and are concurrent at point A.
• The magnitudes of the forces are F1 = 300 N, F2= 200N and F3 = 100 N.
• The line of action of F1 runs from point A to B expressed in Cartesian coordinates.
· F2 has an elevation angle of 30° from the x-y plane. The projection of F2 on the x-y
plane has a 50° transverse angle from the (-)y-axis.
F3 is expressed in coordinate direction angles of a3 = 45°, ß3 = 60°, with
Y3 > 90°.

Draw the exact resultant force in the figure, indicate its moment of force and direction.
Also, locate its intercepts.
Figure 5(a) shows a car seat installation robot. It does the job of three people lifting and
installing the seat as shown in Figure 5(b). 8 = 70° and = 50°. The robot exerts the
wrench resultant of the forces exerted by the three people. Determine this wrench resultant.
Your answer must include the rectangular component (Cartesian) form of the resultant
force, the magnitude of the moment collinear with this resultant force and the coordinates of
point P on the y-z plane through which the resultant force acts.
