Problem 009
The body on the 30° incline in Fig. P-009 is acted upon by a force P inclined at 20° with the horizontal. If P is resolved into components
parallel and perpendicular to incline and the value of the parallel component is 1800 N, compute the value of the perpendicular component
and that of P.
