A horizontal line PQRS is 12 m long, where PQ = QR=RS=4 m. Forces of 1000 N, 1500 N, 1000 N, and 500 N act at P, Q, R, and S respectively with downward direction. The lines of action of these forces make angles of 90°, 60°, 45° and 30° respectively with PS. Find the magnitude, direction, and position of the resultant force.
